Question

Use the numbers 1, 2, 3, 4, 5, and 6 to write a subtraction expression with two mixed numbers that have a difference of less than 2. Simplify your expression.

a) 5×4/3-2×1/2
b) 6×2/3-4×1/2
c) 3×5/6-1×3/4
d) 4×4/5-2×3/8

Answer 1

The correct expression is d) 4×4/5 - 2×3/8. To simplify the expression, multiply the numbers, convert the fractions to have a common denominator, and subtract the fractions. The simplified expression is 49/20.

Step-by-step explanation:

The correct expression is d) 4×4/5 - 2×3/8.

To simplify the expression, we will first multiply the numbers:

4×4/5 = 16/5

2×3/8 = 6/8 = 3/4

Next, we will subtract the two numbers:

16/5 - 3/4

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 20. We can convert both fractions to have a denominator of 20:

16/5 = 64/20

3/4 = 15/20

Now, we can subtract the fractions:

64/20 - 15/20 = 49/20

The simplified expression is 49/20.
