There are 147 chocolates in the jar.
Candies = 9
Chocolates = 7
9 + 7 = 16
Candies = 9/16 = 0.5625 * 100% = 56.25%
Chocolates = 7/16 = 0.4375 * 100% = 43.75%
Total items = 336
Candies = 56.25% * 336 = 189
Chocolates = 43.75% * 336 = 147
Answer: 8
Step-by-step explanation:
From the question, we are informed that Sandy has 6 sheets of colored paper and that she uses 4 sheets to make posters. Therefore she'll have 2 sheets of coloured paper left. This is gotten by : (6 - 4) = 2 sheets.
Since each rectangle is 1/4 of a sheet of colored paper, the number of greetings card that Sandy will make will be gotten by dividing 2 by 1/4. This will be:
= 2 ÷ (1/4)
= 2 × 4
= 8
Sandy will make 8 greeting cards
A simple algebraic equation can be utilized to solve this question. Ayana needs 
yards of blue fabric for each scarf.
Step-by-step explanation:
Step 1; Assume the amount of purple fabric to be x for each scarf and the amount of blue fabric required for each scarf to be y. It says a total of six scarves are needed. It is given that a total of 10 yards of fabric is used i.e. the total of purple fabric and the blue fabric. So we can create an equation for this. As 6 scarves are needed we substitute x and y as 6x and 6y.
Total fabric used= 6x + 6y = 10 yards.
Step 2; It is given that for each and every scarf 1
yards of purple fabric is needed. So for 6 scarves a total of 6 * 1 yards is needed. So 6x becomes 6 * 1 yards.
6x = 6 * 1 yards = 6 * 
= 
yards of purple fabric.
Step 3; Now we solve for the amount of blue fabric needed.
6y = 10 - = 
= 
But the yards is for 6 scarves to we divide it by 6 to get the material needed for a single scarf
y = /6 = * 
= 
= yards = 0.4166 yards of blue fabric for each scarf.
