Sixty-five percent or 39 girls selected going to the movies as their favorite activity how many girls did the reporter survey

Hi!

We will solve this using proportions, like this:

65% = 0,65 39 girls

100% = 1 x girls

x = (39*1)0,65 = 39/0,65

x = 60

Reporter surveyed 60 girls in total.

Hope this helps!

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
