Question

Kesia knows that 1/4 = 0.25. Explain how she could use this fact to determine the decimal equivalent of 5/8.

Answer 1

Well, Kesia can use that information to solve for 5/8. 1/4= 2/8. We know that there must be over .50 in 5/8. We can divide .25 in two to determine what 1/8 would be. 1/8=0.125 (.25/2) .50+ 0.125= .625

I hope this helps you!

Answer 2

Well if you split 1/4 in half then that will give 1/8. You must also split 0.25 in half which gives 0.125
$\frac{1}{8} = 0.125$
Now you can multiply that by 5 which gives 5/8. But also the fraction
$\frac{1}{8} \times 5 = 0.125 \times 5 \\ \frac{5}{8} = 0.625$
Now we know that 5/8 = 0.625
