part a: Lucy makes pottery to sell. One week , she uses 6 3/4kg of clay next week 2 2/3 clay. HOW much does she use during 2 weeks ? part b : The clay is in blocks that weigh 12 kg. How much clay does lucy have left after using clay for 2 weeks ?

6 3/4+2 2/3=27/4+8/3=(27*3+8*4)/12 you do it.

sorry lost, first time ever doing this. can you explain

Which part haven't you done before?

To add fractions, they must have the same denominator. Study this site carefully.

6 3/4 + 2 2/3 = 6 9/12 + 2 8/12 = 8 17/12 = 9 5/12

THANK YOU FOR THE SITE. WILL DEFINTELY GO OVER IT

To solve these questions, we will perform some calculations.

Part a: How much clay does Lucy use during 2 weeks?

To find out how much clay Lucy uses during two weeks, we need to add the amount of clay she uses in each week.

First, let's calculate the sum of 6 3/4 kg and 2 2/3 kg:

6 3/4 kg + 2 2/3 kg

To add these fractions, we need to convert them to have a common denominator. In this case, the lowest common denominator is 12. Let's convert the fractions first:

6 3/4 kg = 6 kg + 3/4 kg = 6 kg + 9/12 kg = 6 kg + 0.75 kg = 6.75 kg

2 2/3 kg = 2 kg + 2/3 kg = 2 kg + 8/12 kg = 2 kg + 0.67 kg = 2.67 kg

Now, let's add these two amounts:

6.75 kg + 2.67 kg = 9.42 kg

During two weeks, Lucy uses a total of 9.42 kg of clay.

Part b: How much clay does Lucy have left after using clay for 2 weeks?

To find out how much clay Lucy has left after using clay for two weeks, we need to subtract the amount she used from the total amount she had at the beginning.

If the clay is in blocks weighing 12 kg, we can calculate the total amount she had at the beginning by adding the clay used in two weeks:

9.42 kg + 9.42 kg = 18.84 kg

Now, let's calculate how much clay Lucy has left:

Total amount at the beginning - Total amount used

12 kg - 18.84 kg = -6.84 kg

After using clay for two weeks, Lucy seems to have a negative amount of clay, which doesn't make sense. It's likely there was an error in the calculations or information given. Please check the numbers again or provide more information to re-calculate correctly.
