Question 1 : (7⅗ of 17∕ 19) ∕ 15∕25
Question 2 : An improper fraction is classified as
Question 3 : Simplify without using table log₅12.5 + log₅2
Question 4 : Which of the these is an imaginary
√-4
√9
25
3⅖
Question 5 : 1 6∕9 of ⅔ - 3⅕ + 2½ ∕ ½
1. (7⅗ of 17∕ 19) ∕ 15∕25
7 3/5 = 38/3
And "of" means " multiply" ......so.....
(38/3) * ( 17/ 19) = (38/19) * ( 17/3) = 2 * (17/3) = 34 / 3
And ( 34/3 ) / ( 15/25) = (34/3) * (25/15) = 170/9 ≈ 18.888 [8's repeating ]
3. log5 (12.5) + log5 (2) = log (12.5 * 2) = log5 25 = 2
4. √-4 is imaginary
2. An improper fraction is classified as a fraction wherein its numerator is greater than or equal to the denominator.
Ex:
1) 7/4
2) 9/2
3) 6/6
etc.
