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.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
