Question

Cost of 3.5 packs of bread is $ 35.35. Find the cost of one pack of bread.

• A. $ 10
• B. $ 10.1
• C. $ 10.2
• D. None of these

Answer 1

The correct option is B $ 10.1

Given,
Cost of 3.5 packs of bread = $\$$ 35.35
Cost of one pack of bread $=\frac{35.35}{3.5}$
Step 1: Get rid of decimal from the divisor.
$\frac{35.35}{3.5}=\frac{35.35\times 10}{3.5\times 10}=\frac{353.5}{35}$
Step 2: Count the number of digits after the decimal in dividend

Step 3: Ignore a decimal point and perform the long division, as you would with whole numbers as follows

Step 4: Now place a decimal point back.
353.5 has 1 decimal places. So, place the decimal point 1 places to the left in the quotient 101

Hence, the cost of 1 bread pack is $\$$ 10.1
