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?

3 answers

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.
