Answer:
1. 72 to 56
2. 90 to 70
Explanation:
To fill in the blanks you need to find similar ratios,
For the first one, the ratio is 72 and ___,
because 72 is in the 9's column, find out what times 9 equals 72,
9 × ? = 72
Simply divide to find the answer,
72 ÷ 9 = ?
= 8
Now that you know that 9 is being multiplied by 8, multiply 8 and 7 together,
8 × 7
= 56
Hence the answer is 56 for the first blank,
For the second one, the ratio is 90 and ___,
because 90 is in the 9's column, find out what times 9 equals 90,
9 × ? = 90
Once again simply divide to find the answer,
90 ÷ 9 = ?
= 10
Now that you know that 9 is being multiplied by 10, multiply 10 and 7 together,
7 × 10
= 70
Hence the answer is 70 for the second blank,
