# Math Help - help plz, fractions

1. ## help plz, fractions

(2)^2 . (25)
(5) (16)

how do i multiply this??

5 + 2
3

how do i do this because i cant find a way how 3 can become a 1 i seriously hate fractions and this is suppose to be a damn review ahhhhh!

2. I don't really get what you are asking

If this is what you are asking (how do i multiply this??):
(2)^2 . (25) = 4 x 25
(5) (16) = 5 x 16

What are you asking for the below? Is it a fraction or??????
5 + 2
3

If you mean (2^2*25)/(5*16), then you should use that 25=5*5 and 16=4*4:

(2^2*25)/(5*16)=(4*25)/(5*16)=(4*5*5)/(5*4*4)=5/4

You can also do it like this:

(2^2*25)/(5*16)=(4*25)/(5*16)=(4/16)*(25/5)=(1/4)*5=5/4

If you mean (5+2)/3, then there's no way to simplify it further than to 7/3. Both 7 and 3 are prime numbers. There's no way to express them as a product of two smaller integers, like I did with 16 and 25 above.

Hello,

maybe you have to calculate a sum. Use the lcd(3,1)=3:

$\frac{5}{3}+2=\frac{5}{3}+\frac{6}{3}=\frac{11}{3}$
