The length of a ribbon is 8/9

meter. Sun Yi needs pieces measuring
1/8

meter for an art project. What is the greatest number of pieces measuring
1/8

meter that can be cut from the ribbon? How much ribbon will be left after Sun Yi cuts the ribbon?

Complete the explanation and enter your answers.

8/9 ÷ 1/8

= as a mixed number,
so a maximum of
piece(s) will measure
1/8

meter.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
