Hi Alizabeth
7/1/5
Remember : 7 has a denominator which is 1. However, we can not write 1 under a numerator. That's the reason why we don't see 1 but I always put in your mind it is there.
7/1/15 (now I put so we can what we need to do)
7/1 * 5/1 ( you leave the first one the one it was and switch the second part.)
= 35/1 ( We can leave 1 under the numerator)
For that reason
= 35
Final answer : 35
It was my pleasure to help you Alizabeth, let me know if you have further questions about my answer.
Thanks
