Answer:
Welcome to basic Algebra!
2/5 = x/60
First thing remember is that whatever action you perform on one side, you must also do to the other. To isolate X you can multiply both sides by 60. Remember that a whole number is a fraction over 1.
60/1 * 2/5 = 60/1 * x/60
Multiply top and bottom of each fraction.
120/5 = 60x/60
Then simplify as much as possible . 60x/60 can be reduced to 1x/1 which is the same as x by itself.
X = 24
If this still doesn't make sense, you can try another deductive method. Think about the fraction 2/5. You can expand this to 40/100, which is also known as 40%. You can now find the percentage of a number from a fraction or a decimal as follows:
Take 60.
Multiply by 2 and you get 120.
Divide by 5 and you get 24.
OR
Multiply by the decimal:
60 x 0.4 = 24
