Answer:

1

Step-by-step explanation:

using the rule of exponents

(\frac{a}{b}) ^{-1} = \frac{b}{a} , then

\frac{123}{321} × \frac{456}{654} × \frac{789}{987} × \frac{321}{123} × \frac{654}{456} × \frac{987}{789}

[ \frac{123}{321} × \frac{321}{123} = 1 , \frac{456}{654} × \frac{654}{456} = 1 , \frac{789}{987} × \frac{987}{789} = 1 ]

= 1 × 1 × 1

Kevin uses 36 ounces of dried apples and 18 ounces of
aliina [53]

Answer:

6 containers

6 ounces of fruit snack will be left over

Step-by-step explanation:

1 pound = 16 ounces

⇒ ¹/₂ pound = 8 ounces

Total weight = weight of dried apples + weight of dried cranberries

                     = 36 + 18

                     = 54 ounces

Containers needed = total weight ÷ weight of snacks in one container

                                 = 54 ÷ 8

                                 = 6.75

Therefore, he will fill 6 containers

Snack left over = total weight - (number of containers × weight of snacks one container will hold)

                          = 54 - (6 × 8)

                          = 54 - 48

                          = 6 ounces
