Question

Keri did jumping jacks for ⅗ of a minute and sit-ups for ½ a minute. How many more seconds did Keri do jumping jacks than sit-ups?
PLS HELP AND HURRY

Answer 1

Answer:

so we need to subtract the situps from the jumping jack so

3/5-1/2

first we need to simplify to the same bottom number

6/10=3/5

5/10=1/2

6/10-5/10=1/10

so 1/10 of 60 is

1/10*60=6

Hope This Helps!!!
