If you estimate 342÷7 by using 350÷7 = 50 is 50 greater than or less than the exact answer? how did you decide? it’s 50 and overestimate or an under estimate

The answer will be greater then that because you are increasing by estimating so ur answer will be larger

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

9.8? i'm not really sure
