Your party is expected to have 20 people including you. Each person gets one fork and one spoon. There are 6 spoons in one package and 8 forks in one package. a. What is the least number of packages of spoons you need to buy? What is the least number of packages of forks you need to buy?

Step-by-step explanation:

Since each person will get 1 fork and 1 spoon, we will need 20 forks and 20 spoons.

The lowest multiple of 6 that is above 20 is 24, so we need 4 packages of spoons.

The lowest multiple of 8 that is above 20 is also 24, so we need 3 packages of forks.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
