The ratio between the first and second numbers in the table is 7:5. To find the missing numbers:
For the third row, we can set up a proportion:
7/5 = 42/x
Cross multiplying gives us:
7x = 5 * 42
7x = 210
x = 210/7
x = 30
So the missing number in the third row is 30.
For the fifth row, we can set up another proportion:
7/5 = 84/x
Cross multiplying gives us:
7x = 5 * 84
7x = 420
x = 420/7
x = 60
So the missing number in the fifth row is 60.
