Question

NUMBER (18) write 0.32 as a fraction in simplest form.

is it: 8/25 32/100 32/10 16/5

***********************************************************************

NUMBER (19) write 5/8 as a decimal

is it: 0.58 0.625 1.6 6.25

Answer 1

Re your second question about writing 5/8 as a decimal, an easy way to change a fraction into a decimal is to write the fraction by hand. So hand-writing 5/8 would be writing 5 with a line under it and writing the 8 under the line. Put a closing parenthesis next to the 8 and extend the line under the 5 to the right and you'll have a division figure, with the 8 outside the box. Put the 5 inside the box, put a decimal point after it and add two or three zeros. Put the decimal point on top of the box right above the decimal point inside the box; it's best to do this before you start so you don't forget it. You're now all set to divide 5.000 by the 8 outside the box. So 8 going into 5.000 becomes the decimal .625

This way, you never have to remember whether you divide the top by the bottom or the bottom by the top of a fraction to change it to a decimal. After a few times you won't have to write it down and you should be able to visualize it right away!

Hope this helps - :)

Answer 2

Number 18: 0.32=32/100 , reduced to lowest common denominator would be 8/25

4 is the lowest common number between the 32 and 100.

Number 19: 5/8 as decimal--divide 5 by 8 =0.625
To turn fractions into decimals, always divide the smallest number by the largest.

Answer 3

.32 extends to the hundreths place. So, write 32/100 and reduce. 8/25

The fraction 5/8 is the same as dividing 5 by 8. You know 5/8 is less than one, so it's one of your first two options. When you divide, you get .625, or you can just work it out as far as .6 since that's the only similar answer.

Answer 4

8/25

Answer 5

18. 8/25, for this reason.
.32 is equal to 32 hundreths, or 32/100. Simplify that by dviding it by the GCF (greatest common factor), and you end up with 8/25.

19. .625 ...I used a calculator =D just divide 5 by 8.

Answer 6

18.=8/25 19= 6.25

Answer 7

8/25 .625
