Question and answer
Jane is making a suit which requires 2 5/8 yards for the jacket and 1 3/4 yards for the skirt. What is the total amount of material she needs? A. 3 1/2 yards B. 4 3/8 yards C. 3 2/3 yards D. 4 yards
Put the fraction in original form, so the 2 5/8 will b read as 21/8 and the 1 3/4 is 7/4. [ The next step u have to do is just add the two using any method u know for adding fraction, but for now, i will use cross multiplication 21/8+7/4 = {(21x4)+(7x8)} / 8x4 = 84+56/32 = 140/32 = 4.375 or 4 3/8 ]

User: 7 1/5 – 6 2/5 = ? A. 1 1/5 B. 4/5 C. 13 3/5 D. 1 4/5

Weegy: These are mixed numbers: integer and fraction. You can solve this performing the subtraction on the fraction part. That is: 1/5 - 2/5. But 1/5 is less than 2/5. So, what you do is to borrow 1 from 7. [ Now, you have 1 + 1/5 = 6/5, and 6/5 - 2/5 = 4/5 is the answer. ]
