a) \( 65-15: 5=65-3-62 \)

Let's simplify both sides of the equation step by step. Starting with the left side: \[ 65 - 15 : 5 \] First, we need to perform the division: \[ 15 : 5 = 3 \] Now substitute that back into the equation: \[ 65 - 3 = 62 \] Now, let's simplify the right side: \[ 65 - 3 - 62 \] First, calculate \( 65 - 3 \): \[ 65 - 3 = 62 \] Now substitute that back into the equation: \[ 62 - 62 = 0 \] So, the right side simplifies to: \[ 0 \] Now we compare both sides: Left side: \( 62 \) Right side: \( 0 \) Since \( 62 \neq 0 \), the equation \( 65 - 15 : 5 = 65 - 3 - 62 \) is not true.
