3 10 in . = 7 8 mi . what is the unit rate

Sav [38]

Answer: (3/10) in = (7/8) mi

1 in = (7/8) mi ÷ (3/10)

= 7/8 * (10/3) = 70/24

1 in = (70/24) mi

It means every 1 inch on the map drawing represents (70/24) miles ≈ 2.917 miles in reality.

Hope this helps :)

How do I find the property of 34+0+18+26

AlladinOne [14]

We have to check which of PEMDAS rules can be applied in this case. We have only ADDITION. In this case we can observe that addition is:
1. Associative $(34+0+18)+26 = 34+(0+18+26)$
2. Commutative $34 + 0 + 18+ 26 = 26 + 18 + 34 + 0$
3. has Additive property $34 +0 = 34$
