Answer:21/50 and 37.5/100
First, we have to find out what 42 as a fraction would be. Since percent goes out of 100, the fraction is 42/100. Both 42 and 100 can fit into 2. So the simplified fraction would be 21/50.
Lastly, to find the percentage for 3/8, you have to find the base percentage. To find this, use 1/8 as a starting fraction. Now, you are trying to find the percentage for 1/8. To find this, divide the denominator by 100. 100÷8=0.125. This cannot be a percentage because it is over 100. So, you have to move the decimal to the right 2 times. Now, the percentage of 1/8 is 12.5%. Since we are trying to find 3/8, we have to multiply the percentage of 1/8 by 3. That gives 37.5%. This is a decimal, so it cannot be simplified.
Hope this helps!
