On Saturday a restaurant used 10 7 ⁄ 9 cans of vegetables. On Sunday they used another 3 4 ⁄ 6 cans. What is the total amount of
Rudik [331]

Answer:

14   4/9  cans

Step-by-step explanation:

We need to add the cans used on Saturday and Sunday

10 7/9 + 3 4/6

We can simplify the fraction 4/6 by dividing the top and bottom by 2

10 7/9 + 3 2/3

To add, we need the fractions to have a common denominator of 9

10 7/9 + 3  2/3*3/3

10 7/9 + 3 6/9

Add the whole numbers  10 +3 = 13

Add the fractions  7/9 + 6/9 = 13/9

    13/9  = 1   4/9

Move the whole part of the fraction to the whole numbers

13 + 1 + 4/9

14  4/9
