first you would have to estimate the division problem once you do that just move your decimal 2 spaces to the right for example if you have four eighths you would round four to five and eight to ten and then you divide

For multiplication or division, the only reasonable estimate is -2.

Either or both.

An estimate is related to a number, not an arithmetic operation. Having said that, the estimate MUST take account of the context of the operations (+-*/).

For multiplication or division it is 0.5For addition or subtraction it depends on the other term(s). If adding to 1234 I would estimate 0.457 as 0 but if adding to 0.0000035 I would estimate it as 0.46

Anything divided by itself equals 1.

For addition or subtraction, 1 but for multiplication or division, 1.25

For multiplication or division, 133.33... or 100*4/3

The word estimate is for a number, irrespective of the arithmetical operation involved. However, how you estimate for a number DOES depend on the operation. For example, if adding (or subtracting) 0.00496 form 123456, I would estimate 0.0049 as 0. But, it multiplying or dividing I would estimate it as 0.005 - it all depends on the context of the arithmetic operation.

You wouldn't have to estimate for addition, subtraction or multiplication. For division, use 30/5 = 6

The answer is no, whichever way you choose to do the division: 8 ÷ 620 = 0.012903226 620 ÷ 8 = 77.5
