I need help it is confusing?????
algol [13]

Answer:

1. 7

2. 15

3. 181

Step-by-step explanation:

Just make sure that you make your denominator a whole number

1. 9.8/1.4....,you multiply by 10...which only removes the comma but it keeps the structure of the question

Always remember that what you do to the denominator...you also do to the numerator

: 9.8/1.4 × 10/10 = 98/14 = 7

2. 40.5/2.7....,you multiply by 10

: 40.5/2.7 × 10/10 = 405/27 = 15

3. 3.62/0.02...., you multiply by 100

: 3.62/0.02 × 100/100 = 362/2 = 181

Every 2/3 hour, Harris can sew 1/6 pair of jeans. What is Harris's rate in pairs of jeans per hour?
STatiana [176]
Whole hour - 2/3 = 1/3

1/3 + 1/6 = 2/6 + 1/6
              = 3/6

Harris can sew half of a pair of jeans per hour.
