Jamie had 4/5 of a spool of twine. He then used 1/2 of a spool of twine to make friendship knots. Over. Explain how you know whether jamie's Claims is reasonable

Jamie's claims are correct because 3/10 of the spool twine is left over after using 1/2 of the spool twin for friendship knot

Step-by-step explanation:

Full question: He claims to have 3/10 of the original spool of twine leftover.

First, we compare 3/10 with 4/5 - 1/2

The lowest common multiple for2 and 5 is 10.

To write 4/5 as a fraction with common denominator, multiply numerator and denominator by 2

4/5 = (4*2) / (5*2) = 8/10

To write 1/2 as a fraction with a common denominator, multiply denominator and numerator by5

1/2 = (1*5) / (2*5) = 5/0

So we have:

8/10 - 5/10

Since denominators are equal, we go ahead and subtract

8/10 - 5/10 = (8-5) / 10 = 3/10
