4 3/20-5 2/5=4 3/20-5 8/20==-1 1/4

3 1/8-1 5/48=3 6/48-1 5/48=2 1/48

2 1/48-1 1/4=2 1/48-1 12/48=37/48

Answer 2

Ответ:

37/48

Пошаговое объяснение:

Нод 240

3 30/240 + 4 36/240 - 1 25/240 - 5 96/240 = 7 66/240 - 6 121/240 =(306-121)/240= 185/240=37/48

3 6/48 - 1 5/48 + 4 3/20 - 5 8/20 = 2 1/48 - 1 5/20 = 2 1/48 - 1 1/4 = 2 1/48 - 1 12/48 = (49-12)/48 = 37/48

Answer 3

To solve the expression (3 1/8 + 4 3/20 - 1 5/48 - 5 2/5), we need to convert all the mixed numbers into improper fractions and then perform the operations.

Let's convert the mixed numbers into improper fractions first:

3 1/8 = 25/8 4 3/20 = 83/20 1 5/48 = 53/48 5 2/5 = 27/5

Now let's perform the subtraction:

25/8 + 83/20 - 53/48 - 27/5

To add or subtract fractions, we need a common denominator. The least common multiple (LCM) of 8, 20, 48, and 5 is 240. Let's convert each fraction to have a denominator of 240:

(25/8) * (30/30) = 750/240 (83/20) * (12/12) = 996/240 (53/48) * (5/5) = 265/240 (27/5) * (48/48) = 1296/240

Now we can perform the subtraction:

750/240 + 996/240 - 265/240 - 1296/240

Combining the fractions:

(750 + 996 - 265 - 1296)/240

Calculating the numerator:

(750 + 996 - 265 - 1296) = 185/240

Simplifying the fraction:

185/240 = 37/48

Therefore, the expression (3 1/8 + 4 3/20 - 1 5/48 - 5 2/5) is equal to 37/48.
