What is the product of −2 1/4 and −4 1/2 ?

1 answer:

4 0

To multiply fracti0ons, we need to convert them to improper fractions:

-2 1/4 = -9/4
-4 1/2 = -9/2

Now, lets multiply:

-9/4 * -9/2 = 81/8

Hope this helps!

Take note that the answer is positive because when multiplying, two negatives make a positive.

Mr. Edwards has a total of 28 kids in his class. There are 6 more boys than there are girls. Write a system

ratelena [41]

Answer:

17 boys and 11 girls

Step-by-step explanation:

Create a system of equations where b is the number of boys and g is the number of girls:

b + g = 28

b = g + 6

Solve by substitution, by substituting the second equation into the first one:

b + g = 28

(g + 6) + g = 28

2g + 6 = 28

2g = 22

g = 11

So, there are 11 girls.

Since there are 6 more boys than girls, there are 17 boys.

So, there are 17 boys and 11 girls in the class.

4. Find the H.C.F. of the following numbers. <br>6. 68,48 b. 64, 128<br>c. 24,54

Goryan [66]

Answer:

Step-by-step explanation:

a)Factors of 6 = 1, 2, 3 and 6. Factors of 9 = 1, 3 and 9. Therefore, common factor of 6 and 9 = 1 and 3. Highest common factor (H.C.F) of 6 and 9 = 3.

he HCF of 68 is 68.....! bcoz 68 itself is a highest factor of 68.....!

48 are 2×2×2×2⇒16

b)64 = 1 × 2 × 2 × 2 × 2 × 2 × 2. 80 = 1 × 2 × 2 × 2 × 2 × 5.

Factors of 128 are 1, 2, 4, 8, 16, 32, 64, 128. There are 8 integers that are factors of 128. The greatest factor of 128 is 128. 3.

c.Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

54 = 2 × 27 = 2 × 3 × 9 = 2 × 3 × 3 × 3. 81 = 3 × 27 = 3 × 3× 9 = 3 × 3 × 3 × 3. 99 = 11 × 9 = 11 × 3 × 3. Factors common to all three numbers is 3 × 3.
