Answer 1

Ответ:

Пошаговое объяснение:

1. 7 1/3+2 1/4=7 4/12+2 3/12=9 7/12

2. 9 7/12:0,25=115/12:1/4=115/12*4/1=115/3=38 1/3-30 5/6=37 8/6-30 5/6=

7 3/6=7 1/2=7,5

Answer 2

To simplify this expression, follow the order of operations (PEMDAS/BODMAS):

1. First, calculate the addition and subtraction inside the parentheses:

7 1/3 + 2.25 = 7.333... (approximately, since 1/3 as a decimal is a repeating decimal) 7.333... + 2.25 = 9.583... (approximately)

2. Next, divide the result by 0.25:

9.583... / 0.25 = 38.333... (approximately)

3. Finally, subtract 30 5/6:

38.333... - 30 5/6

To subtract mixed numbers, you'll first want to convert the whole numbers and fractions into a common fraction:

30 5/6 = (30 * 6 + 5) / 6 = (180 + 5) / 6 = 185 / 6

Now, subtract this fraction from the previous result:

38.333... - 185/6

To subtract fractions, they need a common denominator, which is 6 in this case:

(38.333... * 6/6) - (185/6)

Now, subtract the fractions:

(230/6) - (185/6) = (230 - 185) / 6 = 45/6 = 7.5

So, the simplified result is approximately 7.5.
