Answer 2

To solve the given expressions, let's go through each one step by step:

1) 3/8 • (-2 + 2/3): To solve this expression, we need to simplify the parentheses first. Adding -2 and 2/3, we get -4/3. Now, we can multiply 3/8 by -4/3. Multiplying the numerators and denominators, we get -12/24, which simplifies to -1/2.

2) -1.6 • 5/8: To solve this expression, we need to multiply -1.6 by 5/8. Multiplying the numerators and denominators, we get -8/8, which simplifies to -1.

3) -7/8 • 1 + 1/7: To solve this expression, we need to simplify the multiplication first. Multiplying -7/8 by 1, we get -7/8. Now, we can add 1/7 to -7/8. To add fractions, we need a common denominator. The common denominator for 8 and 7 is 56. Converting -7/8 to have a denominator of 56, we get -49/56. Adding 1/7 to -49/56, we get -49/56 + 8/56 = -41/56. Therefore, the result is -41/56.

4) 4 2/3 • (-3/14): To solve this expression, we need to convert the mixed number 4 2/3 to an improper fraction. Multiplying the whole number (4) by the denominator (3) and adding the numerator (2), we get 14/3. Now, we can multiply 14/3 by -3/14. Multiplying the numerators and denominators, we get -42/42, which simplifies to -1.

So, the solutions to the given expressions are: 1) -1/2 2) -1 3) -41/56 4) -1
