Question

В первый день скосили 3 4/15 га луга, во второй день-на 8/15 га меньше,чем в первый день и на 1 1/15 га меньше ,чем в третий день.Сколько гектаров луга скосили за три дня ?

Answer 1

1) 49/15-8/15=41/15=2 11/15. 2) 2 11/15+ 1 1/15= 3 12/15. 3) 3 4/15+ 2 11/15=6. 4) 6+3 12/15=9 12/15

Answer 2

Calculation of the Area of Grassland Cut in Three Days

To calculate the total area of grassland cut in three days, let's break down the information provided:

- On the first day, 3 4/15 hectares of grassland were cut. - On the second day, the area cut was 8/15 hectares less than the first day. - On the third day, the area cut was 1 1/15 hectares less than the second day.

To find the total area of grassland cut in three days, we need to add up the areas cut on each day.

Let's calculate it step by step:

1. Convert the mixed fractions to improper fractions: - 3 4/15 hectares = (3 * 15 + 4)/15 hectares = (45 + 4)/15 hectares = 49/15 hectares. - 8/15 hectares less than the first day = 49/15 - 8/15 hectares = (49 - 8)/15 hectares = 41/15 hectares. - 1 1/15 hectares less than the second day = 41/15 - 1 1/15 hectares = (41/15 - (1 * 15 + 1)/15) hectares = (41/15 - 16/15) hectares = (41 - 16)/15 hectares = 25/15 hectares.

2. Add up the areas cut on each day: - 49/15 + 41/15 + 25/15 hectares = (49 + 41 + 25)/15 hectares = 115/15 hectares.

Therefore, 115/15 hectares of grassland were cut in three days.
