Problem 1

<h3>Answer:  2/5</h3>

--------------------------

Explanation:

There are 4 green blocks out of 4+6 = 10 total. We divide the number of green over the number total to get the answer. Reduce the fraction as much as possible. The fraction 4/10 reduces to 2/5 (we divide both parts by 2).

====================================================

Problem 2

<h3>Answer: 1/6</h3>

--------------------------

Explanation:

The probability the spinner lands on red is 2/6 = 1/3. This is because there are 2 spaces that are red out of 6 total. It helps to reduce as much as possible.

The probability the coin lands on heads is 1/2 because there's 1 side labeled heads out of 2 total.

Multiply the fractions: 1/3 * 1/2 = 1/6

This works because both events are independent.

How do I solve this math problem?
Alina [70]
You would subtract 11 on both sides of the equation.
Then multiply the reciprocal of 1/2 which is 2.
And you should get -16 as your answer <span />
