Answers and fast which expresses 1550 : 2000 as a decimal? a. 0.08 b. 0.155 c. 0.31 d. 0.775

0.775

Step-by-step explanation:

The quick way of doing this is to simply divide 1550 by 2000. Put it into your calculator as

1550

÷

2000

=

And it gives you 0.775

You could do it a longer but much more instructive way by factoring this into Prime factors.

1550: 2* 5 * 5 * 31

2000: 2 * 2 * 2 * 2 * 5 * 5 * 5

Now cancel out all the common factors.

2 * 5 * 5 is the HCF

31 in the numerator

40 in the denominator

Now divide these two 31 / 40 = 0.775

Either way, the answer is 0.775

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
