Пошаговое объяснение:

10 3/4 - 7= 3 3/4

7 5/7-4 3/7 = 3 2/7

Answer 2

Let's break down these two subtraction problems:

1. 10 3/4 - 7 To subtract a whole number from a mixed number, you can think of the whole number as a fraction with a denominator of 1. So, 7 can be written as 7/1. Now, you can subtract the fractions:

(10 3/4) - (7/1)

To subtract fractions, you need a common denominator, which in this case is 4:

(10 * 4/4 + 3/4) - (7 * 4/4)

Now, you can subtract the fractions:

(40/4 + 3/4) - (28/4)

Now, add the fractions inside the parentheses:

(43/4) - (28/4)

Now, subtract the fractions:

(43 - 28)/4 = 15/4

So, 10 3/4 - 7 = 15/4, or you can convert it to a mixed number:

15/4 = 3 3/4

So, 10 3/4 - 7 = 3 3/4

2. 7 5/7 - 4 3/7 These two mixed numbers already have the same denominator (7), so you can subtract them directly:

(7 5/7) - (4 3/7)

Now, subtract the whole numbers:

(7 - 4) = 3

Now, subtract the fractions:

(5/7 - 3/7)

Since the denominators are the same, you can subtract the numerators:

(5 - 3)/7 = 2/7

So, 7 5/7 - 4 3/7 = 3 2/7
