2. Write two numbers that are opposites and each more than 6 units away from 0.
Yuki888 [10]

Answer:

-7, 7

Step-by-step explanation:

Opposites are basically two numbers that are at different sides of the number line. For example, -2 and 2 are opposites because they are the same distance away from 0 on a number line making them opposites. To make an opposite just take a positive number, and then add a negative to it. (8, -8)

Tom caught 4 fish and his son caught 12 fish. The number of fish that Tom’s caught was what percent of the number of fish his so
Fofino [41]

Answer:

33.3 % (Approx) percent of fish that Tom’s caught  of the number of fish his son caught .

25% is the percent of the total amount Tom caught.

Step-by-step explanation:

Formula

Percentage = \frac{Part\ value\times 100}{Total\ values}

Part First

As given

Tom caught 4 fish and his son caught 12 fish.

Here

Part value = 4

Total value = 12

Put in the formula

Percentage = \frac{4\times 100}{12}

Percentage = \frac{400}{12}

Percentage = 33.3 % (Approx)

Therefore the 33.3 % (Approx) percent of fish that Tom’s caught  of the number of fish his son caught .

Second Part

As given

Tom caught 4 fish and his son caught 12 fish.

Total number of fish caught = 4 + 12

                                              = 16

Part value = 4

Total value = 16

Put in the formula

Percentage = \frac{4\times 100}{16}

Percentage = \frac{400}{16}

Percentage = 25%

Therefore the 25% is the percent of the total amount Tom caught.
