Bob had 18 crackers Sam eat 1/6 of the crackers and sue ate 1/3 of the crackers. how many crackers did Bob have left

Answers

We can add 1/6 & 1/3 together to find out the total amount of crackers that were eaten:

1/6 + 1/3   (Find the Common Denominator. In this case it is 6.) 
= 1/6 + 2/6
= 3/6 (Now find the Lowest Terms. Both 6 & 3 divide into 3)
= 1/2 (In Lowest Terms)

This means that 1/2 of the Crackers have been eaten.

1/2 of 18 = 9 

Therefore, Bob has 9 Crackers left. 
The first thing to do is make both fractions over 6: 
1/3 = 2/6
Sue at 2/6 of the crackers. 

Now we can add the fractions: 
2/6 + 1/6 = 3/6

The next thing to do is cancel down the fraction. 
3/3 = 1
6/3 = 2
3/6 = 1/2

Now that we know that half of the crackers have been eaten, we halve the total amount: 
18 X 1/2 = 18 / 2 = 9

Bob had 9 crackers left. 

Each student will be asked to collect 5 oak leaves, 3 elm leaves, 7 maple leaves, and 6 red ash leaves. Write and solve an equation that can be used to find the total number of leaves, n, that will be collected

Answer:

x=-3

Step-by-step explanation:

Given: 2(x+1)=3x+5

Distributive Property: 2x+2=3x+5

Subtract 2x on both sides: 2=x+5

Subtract both sides by 5: x=-3

Therefore, x=-3

Suppose 2kg of sugar contains 9*10 crystals.How many sugar crystals are there in 5 kg of sugar???2)1.2kg of sugar

Answers

Answer:

225

Step-by-step explanation:

9*10 = 9 times 10 = 90

2kg = 90

that means 1kg = half of 90 = 45

1kg = 45

5 kg = 45 times 5 = 225

By the way at the end of your question you put "2)1.2kg of sugar" but I don't know what that is so i ignored it
