Answer:
The simplified form of given expression is 3/5.
Step-by-step explanation:
The given expression is
We need to find the product of two factions using diagram.
For 3/4, draw a box and divide it in 4 equal parts by using vertical lines. The color three parts of it.
For 4/5, draw a box and divide it in 5 equal parts by using horizontal lines. Then color the four parts of it.
Now combined both boxes and shown below.
From the below figure it is clear that
The number of common shaded small boxes = 12
Total number of small boxes = 20
The required fraction is
Cancel out common factor.
Therefore, the simplified form of given expression is 3/5.
The simple interest rate was: 1.25%
Step-by-step explanation:
Simple interest is given by:
Given
Principal amount =$3000
Time = t = 2 years
Interest amount = A = $75
putting the values in the formula
Dividing both sides by 6000
So,
The rate is:
0.0125 * 100 = 1.25%
Hence,
the simple interest rate was: 1.25%
