A fraction is a number representation that is broken down into two parts - the number on top is called the numerator, and the number on the bottom is called the denominator.

Explanation: We got 0.075 as the answer when you convert \$3/40\$ to a decimal.

The order of operations in math, commonly known as PEMDAS in the US, dictates the proper sequence for solving equations: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Explanation: \$3/5 - 2/6 + 7/4\$ In the above equation, first, we perform the addition operation \$(3/5 + 7/4) = 47/20\$ and then subtraction \$(47/20 - 2/6) = 121/60\$ and then convert decimal number \$121\div60 = 2.01\$.
