Answers:

1.

• First, let's handle the parentheses: (85+ 65) 85 + 65 = 150
• Now we have: 25-55+ 150
• Working from left to right: 25 - 55 = -30 -30 + 150 = 120
• So the left side equals 120.
• For the right side, 5! (factorial of 5) means: 5! = 5 × 4 × 3 × 2 × 1 = 120
• Therefore, 25-55+ (85+ 65) = 5! is a true equation since both sides equal 120.

2.

• First, take the goat across.
• Go back alone and take the cabbage across.
• Bring the goat back.

• Finally, go back and bring the goat over.

• To divide 40 by 1/2: When we divide by a fraction, it's equivalent to multiplying by its reciprocal. So dividing by 1/2 is the same as multiplying by 2.
• 40 ÷ (1/2) = 40 × 2 = 80
• Then adding 15: 80 + 15 = 95
• The answer is 95.
