Question

Look at mina's work below 10 7/12 - 9/12 = (10/12 + 7/12) - 9/12 = 17/12 - 9/12 = 8/12 is mina's solution reasonable. Explain

Answer 1

Mina's solution is not reasonable. The correct solution is 17 5/6.

Step-by-step explanation:

Mina's solution is not reasonable because she made a mistake in simplifying the expression. Let's go through the steps to find the correct solution:

1. Step 1: Add the whole numbers: 10 + 7 = 17
2. Step 2: Add the fractions: 1/12 + 9/12 = 10/12
3. Step 3: Simplify the fraction: 10/12 can be reduced to 5/6

So, the correct solution is 17 5/6, not 8/12 as Mina suggested. It's important to be careful when performing operations with fractions and double-check our work to ensure accuracy.

Answer 2

10 7/12 - 9/12=(10/12+7/12)-9/12=17/12-9/12=8/12

127/12-9/12

Nope. Her solution doesn't seem reasonable. In order to subtract 9/12 from 10 7/12 you must convert 10 7/12 to an improper fraction. You should then have 127/12 where she has 10/12.

Hope this helps! =)
