Let's solve :
therefore, the correct choice is :
Decimals are by 10.
50 x 2 is 100
that means that all you have to do is multiply the numerator by 2 and divide it by 100
23 x 2 is 46
(since the numerator is not larger than the denominator, you put a decimal at the beginning)
the answer is .46

Answer:
Step-by-step: the two triangles are similar, their sides would match up and create the same ratio. However, as you can see
3
5
≠
4
12
≠
5
13
. Each side has a different ratio. Therefore, they don't necessarily have to be similar.
4*4*4*4 so basically putting 4 in 5 groups
10. Not sure what the question is. Looks like it could be to write 9/5 in decimal form? In that case, we have 1/5 = 0.2, so 9/5 = 9*0.2 = 1.8
11. 
. If we round to 5 decimal places, the approximate value is 52.23232
12. By long division, we can show that 
. In repeated decimal notation, that's
