⓵ You run 1 ¾ miles. You can decide to work with fractions, but I find it easier to work with decimals :
¾ = 3 ÷ 4 = 0,75
1 mile + 0,75 mile = 1,75 miles
⓶ Your friend runs 4 times as far as you do, wich means that he runs 1,75 miles times four :
1,75 x 4 = 7 miles
So your final answer is : Your friend runs 7 miles each day.
I hope this helped, if there’s anything just let me know! ☻
