Two numbers are in the ratio 3:7 if the larger number is 42 then find the smallest number
42(3/7) = 18
To find the smaller number in the ratio of 3:7, we can set up a proportion and solve for the unknown.
Let's assume the smaller number is x.
According to the given ratio, we have:
3/7 = x/42
To solve for x, we can cross-multiply:
3 * 42 = 7 * x
126 = 7x
Divide both sides by 7:
126/7 = x
x = 18
Therefore, the smallest number is 18.
To find the smallest number in the ratio 3:7 when the larger number is 42, we need to set up a proportion and solve for the unknown.
The ratio 3:7 can be written as 3/7. Let's represent the smallest number as 'x'. So, we have the proportion:
3/7 = x/42
To solve for 'x', we can cross-multiply:
3 * 42 = 7 * x
126 = 7x
Finally, divide both sides of the equation by 7:
x = 18
Therefore, the smallest number in the ratio 3:7 when the larger number is 42 is 18.
