Answer:
The purpose of this task is to help students see the connection between a÷b and ab in a particular concrete example. The relationship between the division problem 3÷8 and the fraction 38 is actually very subtle.
3÷8 is the number you multiply 8 by to get 3.
38 is the number you get by taking 3 copies of the unit fraction 18.
So 3÷8 is defined in terms of multiplication, and 38 is defined in terms of unit fractions. It is not obvious that these two numbers are the same, so students need opportunities to see that they will necessarily always be the same. Note that if b people share a pies equally, then each person will get ab of a pie by the same kind of reasoning shown in the solution below.
This task is probably best suited for instruction or formative assessment.

31% is spent on food.
Subtract that from his income of 100%
you get 69%
Multiply 69% by his income, and you get $7762.5
Answer:
f(12) = 11
Step-by-step explanation:
To solve this question:
- Substitute x = 12 into the equation: f(12) = 3/4 (12) + 2
- Simplify: 3/4 × 12 = 36/4 which is 9 → f(12) = 9 + 2

The difference between the amounts of interest Marcus and Gianna paid for their car loan is $50
<h3>The amount and simple interest</h3>
The formula for calculating the amount on simple interest is given as:
A = P + I
I = PRT
A = PRT + P
Given the following paramteers
A = 10000(0.047)(5) + 100000
A = 2350 + 10000
A = 12350
For Gianna
A = 10000(0.045)(5) + 100000
A = 2250 + 10000
A = 12250
Difference = 12350 - 12250 = $50
Hence the difference between the amounts of interest Marcus and Gianna paid for their car loan is $50
