Change 45% to a decimal.

To find 3 percent of 60, calculate 3% as a decimal, which is 0.03, and then multiply it by 60:

0.03×60=1.8

This means 3 percent of 60 is 1.8.

The correct answer is: C 1.8

Use the conversion factor where;

1 kilogram equals 1000 grams.

Given 2 kilograms, the conversion to grams is:

2kilograms×1000grams/kilogram=2000grams

Thus, 2 kilograms is equivalent to 2000 grams.

The correct answer is: B 2,000 grams.

To find average items to be sold per day, divide the total items to sell by number of selling days remaining.

Averageitemsperday=TotalitemstosellNumberofsellingdays

Substitute the given numbers into the formula:

Items to sell – 63

Number of selling days – 18

Averageitemsperday=

Now, perform the division:

Averageitemsperday=3.5

Since all the items are not in fraction, round up to the next whole number.

Thus, the salesman needs to sell an average of 4 items per day.

The correct answer is: B 4

Calculate the total number of people needing servings:

70(students)+3(staff)=73people

Each cake provides 24 servings.

Divide the total number of people by the number of servings per cake and then round up to the nearest whole number (because you can't order a fraction of a cake):

73 ÷ 24 ≈ 3.04

Since you can't have a fraction of a cake, round up to 4 to ensure there are enough servings for everyone. Thus, the committee should order:

4 cakes.
