1 3/8 - 5/8 - 3 1/8 with the remainders

Answer 1

To subtract mixed numbers with remainders, start by subtracting the whole numbers and the fractions separately. Then, subtract the remainders if necessary.

1 3/8 - 5/8 - 3 1/8
= (1 - 3 - 3) + (3/8 - 5/8 - 1/8)
= -5 + (3/8 - 5/8 - 1/8)
= -5 + (-3/8)
= -40/8 + (-3/8)
= (-40 - 3)/8
= -43/8

So, 1 3/8 - 5/8 - 3 1/8 with the remainders equals -43/8.

Answer 2

4/5 + 7/15 + 3/5
Answer choices
1 2/5
7/10
1 13/15
14/15

Answer 3

To add the fractions, first find a common denominator. In this case, the common denominator is 15.

4/5 + 7/15 + 3/5
= (12/15) + (7/15) + (9/15)
= 12/15 + 7/15 + 9/15
= (12 + 7 + 9)/15
= 28/15

Since the numerator is greater than the denominator, we can simplify the fraction by dividing the numerator by the denominator and finding the remainder:

28 ÷ 15 = 1 remainder 13

So the simplified fraction is 1 13/15.

Therefore, the answer is 1 13/15.

Answer 4

-14 times (-32)

Answer 5

To find the product of -14 and -32, multiply the two numbers together:

-14 × -32 = 448

Therefore, -14 times -32 equals 448.

Answer 6

6/7 times 42.21

Answer 7

To find the product of 6/7 and 42.21, multiply the fraction by the decimal:

6/7 × 42.21

To multiply a fraction by a decimal, multiply the numerators together and multiply the denominators together:

(6 × 42.21) / (7 × 1)

= 253.26 / 7

= 36.18

Therefore, 6/7 times 42.21 equals 36.18.

Answer 8

-3/8 times 1 1/2

Answer 9

To find the product of -3/8 and 1 1/2, first convert 1 1/2 to an improper fraction:

1 1/2 = 3/2

Now, multiply -3/8 by 3/2:

(-3/8) × (3/2)

To multiply fractions, multiply the numerators together and multiply the denominators together:

((-3) × 3) / (8 × 2)

= -9/16

Therefore, -3/8 times 1 1/2 equals -9/16.
