Answer:
10
3.59
6 7/12
Step-by-step explanation:
4 - (-6)
= 4+ 6 ( because when we multiply the negative sign with the negative sign we get a positive sign or a plus sign)
= 10
-2.5 + 6.1 -10.3 - (-7.79) -4 + 6 1/2
= -2.5 + 6.1 -10.3 +7.79 -4 + 6.5 [ (-*-=+) ( converting 6 1/2 into decimal = 6.5)]
= 6.1+7.79+ 6.5 -2.5 -10.3-4 { adding the + numbers and - numbers separately}
= 20.39 - 16.8 { subtracting the totals of + and - numbers}
= 3.59
8 5/6 + (-2 1/4)
= 53/6 - 9/4 { Converting into improper fractions}
= 53( 2) - 9(3)/12 { Taking LCM = 12}
= 106-27/12
= 79/12
= 6 7/12
{ Converting into improper fractions and vice versa}
- we multiply the denominator with the whole number and add it to the numerator to get the improper fraction.( 8 5/6= 53/6)
- we divide the numerator with the denominator the answer gives the whole number and the remainder gives the numerator of the proper fraction. ( 79/12 = 6 7/12)
{ Taking LCM = 12}
Factors of 6 are 3 and <u>2</u>
Factors of 4 are 2 and <u>2</u>
Least Common Multiple is taking the common factors and multiplying it with the rest . 2 is common in both . It will be taken once and then multiplied with the other 2 and 3 so we get
LCM = 2*2*3= 12
No real solution
you must take the square root of a -3 which gives you an imaginary number
Answer:
3 to 12 and 1 to 4:
Step-by-step explanation:
3 to 12 would be = 3:12
1 to 4 would be = 1:4
Since ratios can also be fractions, think of it this way. 3:12 as 3/12, and 1:4 as 1/4.
Now, if you simplify, you will see they are equivalent to each other,
3/12 = 1/4
Question 1: X = 2/3
Question 2: X = 4
Question 3: X = 48
Question 4: ?
Question 5: X = 1
Question 6: Yes
Question 7: No
Question 8: No
Question 9: Kara (Danvers is always right) < ignore that
Question 10: X = 0.5
Hope this helped!
