How many twentieths would be the same as five tenths?

Answer 1

?/20 = 5/10

The easy way when we have equal fractions with 1 missing piece is to use cross-multiplication.

Multiply the top number of ?/20 by the bottom number in 5/10. and then, multiply the top number of 5/10 by the bottom number of ?/20.

10*? = 5 * 20

10*? = 100

Now all we have to do, is divide both sides by 10 to find out what our ? is.

? = 10.

This says, 10/20ths = 5/10.

(Your answer would be 10, for your question)

You can also think of it this way. Simplify each fraction if possible.

??/20 = 1/2

How many parts of 20 do you need to have one-half (1/2) of it? That's right, 10!

and 10/20 can be simplified to 1/2
