How to calculate 37 + 125 + 63 + 175 simply

Using the combination law of addition: (37 + 63) + (125 + 175) = 100 + 300 = 400

Calculation: - 30 and 18 / 19 times (- 20)

11760/19
618 18 / 19

-19 and 18 / 19 times 20

First, change the band fraction into a pseudo fraction - 379 / 19, and then multiply by 20. When multiplying by 20, you need to multiply the molecule by 20, that is - 379 times 20 to get - 7580 / 19, that is - 398 and 18 / 19
