Write as improper fraction 22/3
-
(A) 8/3
-
(B) 8/9
-
(C) 3/8
-
(D) 9/8
Correct Answer
A. (A) 8/3Explanation
The given number, 22/3, can be written as an improper fraction, which means the numerator is greater than the denominator. To convert it into an improper fraction, we divide the numerator (22) by the denominator (3). The result is 7 with a remainder of 1. Therefore, the improper fraction is 7 1/3. To write it as a fraction, we multiply the whole number (7) by the denominator (3) and add the numerator (1). This gives us 21 + 1 = 22. So, the fraction is 22/3, which matches option (A) 8/3.Rate this question:

To multiply the fractions 135513 and 13181813, you simply multiply the numerators together to get the new numerator and multiply the denominators together to get the new denominator. Here's how you do it:
135×1318=(13⋅13)(5⋅18)513×1813=(5⋅18)(13⋅13)
Now, calculate the numerator and denominator:
Numerator: 13⋅13=16913⋅13=169 Denominator: 5⋅18=905⋅18=90
So, 135×1318=16990513×1813=90169.
To simplify the fraction, you can find the greatest common divisor (GCD) of 169 and 90, which is 1. Divide both the numerator and denominator by 1:
16990=169÷190÷1=1699090169=90÷1169÷1=90169
The fraction 1699090169 is already simplified, so the result of multiplying 135513 and 13181813 is 1699090169.Rate this question:

To evaluate the sum of 325352 and 223232, you can follow these steps:
Convert the mixed numbers to improper fractions.
Find a common denominator.
Add the fractions together.
Add the whole numbers.
Let's break it down:
Step 1: Convert mixed numbers to improper fractions:
325352 as an improper fraction: 325=(3⋅5)+25=15+25=175352=5(3⋅5)+2=515+2=517
223232 as an improper fraction: 223=(2⋅3)+23=6+23=83232=3(2⋅3)+2=36+2=38
Step 2: Find a common denominator:
The common denominator for 5 and 3 is 15.
Step 3: Add the fractions together:
175+83517+38
Now, we need to find a common denominator, which is 15:
(17⋅3)(5⋅3)+(8⋅5)(3⋅5)(5⋅3)(17⋅3)+(3⋅5)(8⋅5)
=5115+4015=1551+1540
Step 4: Add the fractions with the common denominator:
5115+4015=51+4015=91151551+1540=1551+40=1591
Now, we have the sum of the two improper fractions as 91151591.
To simplify the fraction, you can find the greatest common divisor (GCD) of 91 and 15, which is 1. Divide both the numerator and denominator by 1:
9115=91÷115÷1=91151591=15÷191÷1=1591
So, the final result is 91151591, which can also be expressed as a mixed number:
9115=61151591=6151
Therefore, 325+223=6115352+232=6151 or 91151591.Rate this question:
