${\tt{\purple{\underline{\underline{\huge{Answer:}}}}}}$

c) (- 2) × (- 3) × (- 4) × 5 = - 120

d) (- 3) × (- 4) × (- 5) × (- 1) = 60

e) 3.25 ÷ 0.5 = 6.5

f) 0.5 ÷ 0.25 = 2

Answer 2

Answer:

c) -120

d) 60

e) 6.5

f) 2

Step-by-step explanation:

c) First, multiply the negative integers.

Here, negative integers are multiplied with each other 3 times, which results in a negative number: -24.

Now multiply this with positive integer (5) as positive integer doesn't change the sign of the product.

Remember, positive*positive=positive

negative*positive= negative (here we can see positive doesn't matter the sign of the product)

negative*negative=positive

When even number of negative numbers are multiplied, it gives positive and odd number of negative numbers multiplied with one another gives negative.

d) The answer comes in positive, as there are 4 negative numbers, and 4 is even.

e) 3.25÷0.5= 325/50= 325*2/50*2= 650/100= 6.5

f) 0.5÷0.25= 5/2.5= 50/25= 2

Hope this helps :)
