Question

Can someone please help me because my teacher didn't teach us this.​

Answer 1

53) 20

because 2-3 has 6, 4-5 has 10, 6-7 has 3, and 8-9 has 1 so... 6 + 10 + 3 + 1 = 20

54) 70%

because you set up a proportion. 14/20 = ?/100. 14 * 100 = 1400/ 20 = 70

( im pretty sure 52 is 8-9, sorry if im wrong.)
