of a jar of strawberry jam. write 5/12 and 3/8
using a common denominator.

The answers are 10/24 and 9/24.

Step-by-step explanation:

Given:

Tim has 5/12 of a jar of blackberry jam and 3/8  of a jar of strawberry jam.

Now, to write using a common denominator.

So, we get the multiples of denominator of the fractions to get common denominator:

12 - 12, 24, 36.

8  -  8, 16, 24.

Here we see that 24 is the common denominator.

Now, we multiply the numerator and denominator with the same number to get the common denominator of the fractions:

⇒  

⇒  

Therefore, the answers are 10/24 and 9/24.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
