Which division problem would have an estimated quotient of 3.5 if the divisor and dividend were rounded to the nearest whole number? a) 7.8 divided by 27.7 b)20.6 divided by 70.19 c)5.9 divided by 21.96 d)15.47 divided by 56.4

A) 7.8 divided into 27.7

Step-by-step explanation:

Rounding 27.7 to the nearest whole number makes it 28.

Rounding 7.8 to the nearest whole number makes it 8.

Dividing 28 by 8, we see that 8 goes into 28 3 times.  Since 8(3) = 24, this makes the remainder 28-24 = 4.

This means the quotient of the rounded numbers is 3 4/8, which is 3 1/2 or 3.5.

answer: the common difference is -0.10

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
