Answer: 21.6 m

Step-by-step explanation:

Given

A football field measures 100\ m\times 72\ m

If a football field similar in shape to a full size  has a length l=30\ m

The ratio of the length of the original to the small field is the same

Assume the width of the small field is  w

\therefore \dfrac{100}{30}=\dfrac{72}{w}\\\\\Rightarrow w=30\times \dfrac{72}{100}\\\\\Rightarrow w=21.6\ m  

Thus, the width of the field is 21.6 m

Answer:

24 with a remainder of 1

Step-by-step explanation

so first you have to bring down the 3 so it is next to the six, and then you divide 36 by 15 and that equals 2. So you right a 2 on top. Then you have to multiply 2 and 15 and that equals 30 so you put a 30 below the 36. After you subtract, it equals 6 then you bring down the 1. Now you divide 61 and 15. The answer is 4 so you put a 4 on top next to the 2. After that you multiply 15 by 4 and that equals 60. You subtract 60 from 61, and you are left with a remainder of 1
