Show the calculation you would use to convert the following: . a.) 0.25m to centimeters. b.) 9.8g to kilograms. c.) 35ms to seconds. d.) 4.2dl to liters

In all of these cases you can use proportions:

1.

1m - 100 cm,

0.25m - x cm.

Then, cm.

2.

1 kg - 1000 g,

x kg - 9.8g.

Then, kg.

3.

1 sec -- 1000 ms,

x sec - 35 ms.

Then, sec.

4.

0.1 L - 1 dL,

x L - 4.2 dL.

Then, L.

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
