Answer:

3/4 or 0.75

Step-by-step explanation:

Is it -45/40 + 1.875?

so -45/40 = -9/8 = -1.125

- 1.125 + 1.875 = 0.75 or 75/100 or 3/4

Another way to solve it

1.875 can be simplified by 1875/1000

bot numerator and denominator are divided by 25 so 1875/1000 = 75/40

so -45/40 + 75/40 = (75 - 45)/40 = 30/40 = 3/4

Anna11 [10]

Answer:

2/7=0.285714

3/7=0.428571

4/7=0.571428

5/7=0.714285

6/7=0.857142

Step-by-step explanation:

1/7 = 0.142857

2/7=2(1/7)

2/7=2(0.142857)

2/7=0.285714

3/7=1/7+2/7

3/7=0.142857+0.285714

3/7=0.428571

Or

3/7=3(1/7)

3/7=3(0.142857)

3/7=0.428571

4/7=2(2/7)

4/7=2(0.285714)

4/7=0.571428

5/7=5(1/7)

5/7=5(0.142857)

5/7=0.714285

6/7=2(3/7)

6/7=2(0.428571)

6/7=0.857142

Why is 20 to 40 a 100% increase
Oksi-84 [34.3K]

increasing 20 to 40 is the same as increasing 20 by 20 (or itself), so it is a 100% increase. Decreasing 40 to 20 is the same as decreasing 40 by 1/2 or by 20. So it is a 50% increase.

when going from 20 to 40, the number is being doubled, and when youre going from 40 to 20 you are cutting the number in half. 

hope this helped:)
