Answer:
Step-by-step explanation:
The ratios are all 3 father steps to 5 son steps. Then ...
son-steps = 5/3·father steps
son-steps = 5/3·36 = 60
and
father-steps = 3/5·son-steps
father-steps = 3/5·30 = 18
___
As a <em>check</em>, you can realize that the numbers in the first blank, 36:60, are double those in the second blank, 18:30. The first of these, 36:60, is 3 times the row underneath it, 12:20.
3/4 times x=2
times both sides by 4/3 to clear fraction (4/3 times 3/4=12/12=1)
1x=8/3
there are 8/3 of them in 2
