Answer 1

1)=5/9+1/6=13/18
2)=3/16-11/24=9-22/48=-13/48
3)-7/9-2/15=-35-6/45=-41/45
4)-14/25-(-7/10)=-14/25+7/10=7/50
5)2 3/7-(11 2/5)=17/7+7/5=134/35=3 29/35
6)5 12/35-10=-4 23/35
7)2 9/20-4 17/30=29/20-137/30=3 8/60
8)-3 8/9-4 1/2=-35/9-9/2=-151/18=-8 7/18
9)-4 3/6-(-5 5/8)=-27/6+45/8=54/48=1 1/8

Answer 3

Calculating Arithmetic Expressions

Sure, I can help you with that! Let's solve these arithmetic expressions step by step.

1) 5/9-(-1/6) To subtract a negative number, you can change it to addition. So, this becomes: 5/9 + 1/6

The common denominator for 9 and 6 is 18. Now, we can rewrite the fractions with the common denominator: 10/18 + 3/18 = 13/18

So, the result is 13/18.

2) 3/16-11/24

To subtract these fractions, we need to find a common denominator, which is 48 in this case. Then we can rewrite the fractions with the common denominator: 9/48 - 22/48 = -13/48

So, the result is -13/48.

3) -7/9-2/15

To subtract these fractions, we need to find a common denominator, which is 45 in this case. Then we can rewrite the fractions with the common denominator: -35/45 - 6/45 = -41/45

So, the result is -41/45.

4) -14/25-(-7/10)

To subtract a negative number, you can change it to addition. So, this becomes: -14/25 + 7/10

The common denominator for 25 and 10 is 50. Now, we can rewrite the fractions with the common denominator: -28/50 + 35/50 = 7/50

So, the result is 7/50.

5) 2.3/7-(-1.2/5)

To subtract a negative number, you can change it to addition. So, this becomes: 2.3/7 + 1.2/5

First, we need to convert the mixed numbers to improper fractions: 17/7 + 6/5

The common denominator for 7 and 5 is 35. Now, we can rewrite the fractions with the common denominator: 85/35 + 42/35 = 127/35

So, the result is 127/35.

6) 5.12/35-10

First, we need to convert the mixed number to an improper fraction: 182/35 - 10

To subtract a whole number from a fraction, we can express the whole number as a fraction with the same denominator: 182/35 - 350/35 = -168/35

Simplifying the fraction, we get -24/5.

7) 2.9/20-4.17/30

First, we need to convert the mixed numbers to improper fractions: 49/20 - 137/30

The common denominator for 20 and 30 is 60. Now, we can rewrite the fractions with the common denominator: 147/60 - 274/60 = -127/60

So, the result is -127/60.

8) -3.8/9-4.1/2

First, we need to convert the mixed numbers to improper fractions: -35/9 - 9/2

The common denominator for 9 and 2 is 18. Now, we can rewrite the fractions with the common denominator: -70/18 - 81/18 = -151/18

So, the result is -151/18.

9) -4.3/16-(-5.5/8)

To subtract a negative number, you can change it to addition. So, this becomes: -67/16 + 55/8

The common denominator for 16 and 8 is 16. Now, we can rewrite the fractions with the common denominator: -67/16 + 110/16 = 43/16

So, the result is 43/16.

I hope this helps! Let me know if you have any other questions.
