Answer 42

@ribhu

Answer 43

Group the ratios below together by placing equivalent ratios in the same circle. 45%, 15:40, 12 to 32, 4:10, 6 to 8, 27 to 60, 20 to 50, 4

Answer 44

i told u this, 27:60

Answer 45

but you have to pair two ratios together

Answer 46

so say 24:43 is equal to 8:43 that would be a pair

Answer 47

does that make sense @ribhu

Answer 48

45% with 27:60

Answer 49

k

15:40 with 12to 32

Answer 64

15/40 = 3/8

Answer 65

10/25= 4/10

Answer 66

12/32 = 3/8

Answer 67

there should be 4 answers using all 12 of the ratios because I am only given 4 circles to put them in. So three in each pair or triplet
