John is playing with a 4oz toy car. If Mary's toy car is 10x more but 4x less than John's. How much does Mary's toy car weigh?

what kind of math is this

John ----- 4 oz

Mary: 10 times more , so 40 oz
John: 4 times less ???? , poor way of phrasing it, why not say 1/4 of John's?
so 1 oz

Thank you. My teacher did this, not me so I don't know why she phrased it bad.

To find out how much Mary's toy car weighs, we need to calculate the weight of John's toy car first.

Given that John's toy car weighs 4 ounces, Mary's toy car is both 10 times more and 4 times less than John's toy car.

If we consider the "10 times more," we multiply John's toy car weight by 10:
John's toy car weight (10 times more) = 4 oz * 10 = 40 oz.

If we consider the "4 times less," we divide John's toy car weight by 4:
John's toy car weight (4 times less) = 40 oz / 4 = 10 oz.

This means that John's toy car weighs 10 ounces.

Now, to find out how much Mary's toy car weighs, we know that Mary's toy car is 4 times less than John's.

Mary's toy car weight = John's toy car weight / 4 = 10 oz / 4 = 2.5 oz.

Therefore, Mary's toy car weighs 2.5 ounces.
