3/4 picked apples. If 120 students picked apples, how many picked bananas
Oxana [17]

Answer:

40 students picked bananas

Step-by-step explanation:

3/4 picked apples    

1 - 3/4 = 1/4 picked bananas

3/4x = 120

Multiply both sides of the equation by 4/3

4/3 * (3/4x) = 120/1 * (4/3)

x = 480/3

x = 160

                                               Total of 160 students

                                               /                                   \

                                   120 = apples                  160 - 120 = 40 = bananas

40 students picked bananas

Hope this helps :)
