it can either mean scale factor which is less likely. Its most likely to mean significant figure. For example the number 5.7342 to 3 s.f is 5.73... remember its not 3 decimal points its 3 figures only!

s.f. stands for scale factor which you use to enlarge shapes e.g . if a shape had a scale factor of 2 you would measure the distance from the point of enlargement to the corners and times it by 2 because that your scale factor.

hope i helped i'm in year 6 so i could be wrong xx

s.f is significant figure. It is basically like rounding up but in decimal terms. For example is you had 0.324 and it said round to 2 s.f, then you look at the 4 and obviously it is below 5 so you round down and leave it as 0.32.

he's wrong, it stands for significant figure. for example, if you had a number like 3203.2342 and you wanted to round it to 2 s.f it would be 3200 because you use the first 2 numbers.
if you wanted to round 0.00001238 to 2 s.f it would be 0.000012 because zero doesn't count as a significant figure.
hope this helps!

it means significant figures, so if the question is asking you to round 124 to 1 s.f., the answer would be 100.

significant figures e.g if ur number is 45360 to 3 s.f it would be 45400.
You round the end number 1-4 leave the same
5+ round up

s.f means scale factor. if you get 2.08 and need a s.f of 2 you get 2.1.
if you want a s.f of 3 from 0.0399, you get 0.0400
s.f 3 of 0.04345 is 0.0435

please can someone explain what s.f. stands for? i'm confused :/  S.f stands for significant figures. This is similar to founding and is hard to explain so here is an example:

0.00411 to 2s.f

= 0.0041

A significant figure is any number but zero, so to work out the one above, I counted past the zeros and only started counting two significant figures form 4. The 2 significant figures are 41, if the 3rd number was higher than 5, I would round it up to 0.0042, however it wasn't.

Significant figures is used as well as rounding because it is more accurate. For example:
ROUND 0.00411 to 2 d.p (decimal places) is 0.00 <-- tells you nothing

However,

Give 0.00411 to 2 s.f is more accurate, as it is 0.0041 <--- gives more information

I hope that is ok and helps you

S.F stands for scale factor. You use scale factors when enlarging shapes.A scale factor multiplys each of the sides by that particular S.F. For examople S.F2=multiply all the sides by 2.

s.f stands for significant figure so if you have the number 345.986 and it had to to 4 s.f it would bcome 346.0 as you count 4 numbers so 3=1
4=2
6=3
0=4.
also you have to round numbers as well! I hope this is helpful!

please can someone explain what s.f. stands for? i'm confused :/  S.F stand for Significant Figures. They can be used for estimation. An example is 234 to 1s.f is 200 as you change all the digits to 0 apart from the biggest one. With 256 to 1s.f you round it up and it would be 300. With 0.00074 to 1s.f it would be 0.0007 (you don't bother writing the last zero as it does not make a difference). It helps if you want to estimate 263*511. You make both numbers to their significant figures so it is 300*500. Ignore the 0s so it is 3*5 (which is 15) and add the zeroes so the estimation would be 150000.

your probably doing enlargement, s.f stands for significant figure, eg, a triangle has the sides of 3cm 4 cm and 5cm, enlarge them by an S.F 2 meaning times the length of the sides by two, this will result in the triangle having the sides of 6cm, 8 cm,10cm
