how does 8tons = 16000

bc 8 times 2 is 16 and then you just add the 3 zeros.

55 + 55 = 110 Explain: we all know 5+5=10 and we add the one from the ten to the other 5+5 and that equals the same number as 5+5=10 so its 110

how do I know if I need to multiply or dived?

To convert "bigger" units to "smaller" ones, you multiply. To convert "smaller" to bigger, you divide. Pound is something big, and ounce is something small - smaller parts make one big thing - 16 ounces are in a pound. To convert pounds to ounces, you multiply by 16. To convert ounces to pounds, you divide by 16.

Why is it called U.S Customary Units of Weight?

Because units change in every country in the world. For example, in Japan, people don't use inches!

What is the difference between weight and mass?

Weight and mass are used interchangeably, but they don't mean the same thing. Mass is the amount of matter in an object, while weight is the force of gravity by which the earth attracts towards it. So your mass on Jupiter and Earth would be the same, but your weight would be different. But in math levels right now, you can use them interchangeably.

Converting pounds to ounces

1, start text, space, p, o, u, n, d, end text, equals, start color #28ae7b, 16, end color #28ae7b, start text, space, o, u, n, c, e, s, end text

To convert pounds to ounces we multiply the number of pounds by start color #1fab54, 16, end color #1fab54.

Example:

start color #ff00af, 30, end color #ff00af, start text, space, p, o, u, n, d, s, end text, equals, start color #ff00af, 30, end color #ff00af, times, start color #28ae7b, 16, end color #28ae7b, equals, start color #6495ed, 480, end color #6495ed, start text, space, o, u, n, c, e, s, end text

Converting ounces to pounds

1, start text, space, o, u, n, c, e, end text, equals, start fraction, 1, divided by, start color #28ae7b, 16, end color #28ae7b, end fraction, start text, space, p, o, u, n, d, end text

To convert ounces to pounds we divide the number of ounces by start color #1fab54, 16, end color #1fab54.

Example:

start color #ff00af, 112, end color #ff00af, start text, space, o, u, n, c, e, s, end text, equals, start fraction, start color #ff00af, 112, end color #ff00af, divided by, start color #28ae7b, 16, end color #28ae7b, end fraction, equals, start color #ff00af, 112, end color #ff00af, divided by, start color #28ae7b, 16, end color #28ae7b, equals, start color #6495ed, 7, end color #6495ed, start text, space, p, o, u, n, d, s, end text
