When 40% of the girls left the school assembly, the ratio of the number of boys to girls became 3 to 4. If there were w girls when the assembly started, what was the total number of boys when the assembly started?

Answers

Answer 1

Answer: I am pretty sure the answer is 15 boys at the beginning of the assembly.
That would mean that there were 28 girls there, and if 40% of them left, which would mean that 8 left, leaving 20 girls. This would leave the assembly with a 3:4 ratio of boys to girls.

Answer 2

Answer: There were 15 boys at the beginning of the assembly and 28 girls

Mr. Hoya brought 5 watermelons from his grocery store. The watermelons weighed 8 1/4 pound, 9 1/4 pound, 8 7/8 pound, 9 5/8 pound, and 10 3/4 pound. At the party 153 people each ate 1/4 pound serving of watermelon. Was the amount of less than or greater than 8 4/8 or 1/2 pounds? Explain how to solve the problem. Then solve it.

Answers

the amount of watermelon consumed was greater than 8 1/2 pounds.

To determine if the amount of watermelon consumed was less than or greater than 8 1/2 pounds, we need to find the total weight of the watermelons Mr. Hoya brought and then subtract the total amount consumed by the 153 people.

1. Find the total weight of the watermelons:

Total weight = 8 1/4 + 9 1/4 + 8 7/8 + 9 5/8 + 10 3/4

2. Convert all the fractions to a common denominator:

Total weight = (33/4) + (37/4) + (35/4) + (39/4) + (43/4)

3. Add the fractions:

Total weight = (33 + 37 + 35 + 39 + 43) / 4

4. Find the sum:

Total weight = 187 / 4

Now, we'll find the total amount consumed by 153 people:

Total amount consumed = 153 * 1/4

Now, we can compare the total amount consumed to 8 1/2 pounds:

8 1/2 = 17/2 = 34/4

Now, let's compare the values:

Total amount consumed = 153 * 1/4 = 153/4 ≈ 38.25

8 1/2 pounds = 34/4 = 8.5

The total amount consumed (38.25) is greater than 8 1/2 pounds (8.5). Therefore, the amount of watermelon consumed was greater than 8 1/2 pounds.

First add all the watermelon weights together (to add the fourths and the eighths multiply the fourths by 2 (1/4x2=2/8) and add the numerators). Then multiply the number of people (153) by how much they each ate (1/4). Then subtract the total amount eaten (38 1/4) from the total weight (46 3/4) and compare that with 8 1/2... The left overs are actually equal to 8 1/2 pounds :)

Tina buys 3 7/8 yards of material at the fabric store. She uses it to make a skirt. Afterward, she has 1 3/8 yards of the fabric leftover. How many yards of material did Tina use?

Answers

The amount of fabric Tina used after she has a leftover of 1 3/8 yards is 2 1/2 yards.

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Tina buys 3 7/8 yards of material at the fabric store, and after she uses it to make it a skirt she has 1 3/8 yards of the fabric leftover.

Therefore the amount of fabric she used is the difference between the total fabric and the leftover which is,

= 3 7/8 - 1 3/8.

= 31/8 - 11/8.

= 20/8.

= 2 4/8.

= 2 1/2 yards.
