Answer:
Part A. 
Part B. The correct quotient is (3 × 4)
Step-by-step explanation:
Part A.
To divide 84.36 by 12 we look for the Highest Common Factor of the whole number and the decimal portions of the numerator and the denominator individually as follows;

Therefore, dividing 84.36 by 12 gives
= 7.03
When dividing 84.3·y by 12, therefore, we have;

Part B.
The correct quotient should have factors of the numerator
Therefore the divisor 12 should be represented as follows

The correct quotient therefore = (3 × 4)
Answer:
Drip is the only answer
Step-by-step explanation:
Mr. Sato needs 9 magnets.
Explanation:
AS there are 24 students in the science class,
there are <span><span>242</span>=12</span> pair of students.
Mr. Sato wants to give each pair of students 3 magnets
Mr. Sato has already given 9 pairs of students their 3 magnets
Therefore number of pairs of students yet to be given magnets is <span>12−9=3</span>.
For them he needs <span>3×3=9</span> magnets.
