The problem consists of four division calculations with decimal divisors: $768 : 3.2 =$ $961 : 0.08 =$ $60 : 0.005 =$ $343 : 0.06 =$

1. Problem Description

The problem consists of four division calculations with decimal divisors:

$768 : 3.2 =$

$961 : 0.08 =$

$60 : 0.005 =$

$343 : 0.06 =$

2. Solution Steps

To perform division with decimal divisors, we multiply both the divisor and the dividend by a power of 10 to make the divisor an integer.

For $768 : 3.2$, we multiply both by 10:

$768 * 10 = 7680$

$3.2 * 10 = 32$

Then we calculate $7680 : 32 = 240$.

For $961 : 0.08$, we multiply both by 100:

$961 * 100 = 96100$

$0.08 * 100 = 8$

Then we calculate $96100 : 8 = 12012.5$.

For $60 : 0.005$, we multiply both by 1000:

$60 * 1000 = 60000$

$0.005 * 1000 = 5$

Then we calculate $60000 : 5 = 12000$.

For $343 : 0.06$, we multiply both by 100:

$343 * 100 = 34300$

$0.06 * 100 = 6$

Then we calculate $34300 : 6 = 5716.666... \approx 5716.67$.

3. Final Answer

$768 : 3.2 = 240$

$961 : 0.08 = 12012.5$

$60 : 0.005 = 12000$

$343 : 0.06 = 5716.67$
