There are 45 M&M in the bag. Your brother ate 2/3 them. How many did he eat.

well 45/3 = 15 = one-third of the bag.

So, ...

To find out how many M&M your brother ate, we need to calculate 2/3 of the total number of M&M in the bag.

Step 1: Calculate 2/3 of 45
To find 2/3 of a number, you multiply the number by 2 and divide that result by 3.
2/3 * 45 = (2/3) * 45 = (2 * 45) / 3 = 90 / 3 = 30

Therefore, your brother ate 30 M&M.

To find out how many M&M's your brother ate, you can follow these steps:

Step 1: Determine the fraction of M&M's that your brother ate. In this case, he ate 2/3 of the total.

Step 2: Calculate the number of M&M's he ate by multiplying the fraction (2/3) by the total number of M&M's (45).

To do this calculation, you can use the following formula:

Number of M&M's eaten = Fraction eaten × Total number of M&M's

Substituting the values:

Number of M&M's eaten = (2/3) × 45

To simplify the calculation, you can convert the fraction 2/3 into decimal form:

Number of M&M's eaten ≈ 0.6667 × 45

Multiplying these values together:

Number of M&M's eaten ≈ 30

Therefore, your brother ate approximately 30 M&M's from the bag.
