Answer:
5) b) 20 1/2
6) a)1/2
Step-by-step explanation:
Method for question 5:
Let's convert the mixed numbers to improper fractions
4 5/9 = 41/9 (that is; 4 x 9= 36, 36 + 5 = 41)
4 1/2 = 9/2 ( that is 4 x 2 = 8, 8 + 1 = 9)
Now we have to multiply them
41/9 x 9/2 = 41/2 (the 9 as the denominator of the 1st fraction gets cancelled with the 9 as the denominator of the 2nd fraction)
Now we have to divide 41 by 2
41/2 = 20.5
0.5 can also be written as 1/2 (this is done as we need the answer as a mixed number)
so the answer is 20 1/2
Method of question 6:
For this we should follow BODMAS ( Brackets, Of, Division, Multiplication, Addition, Subtraction)
Since division comes before multiplication, we should calculate 1/2 divided by 3/8
That also means 1/2 x 8/3 = 4/3 (division of fraction is also similar to the multiplication of t he reciprocal of the fraction and we can cancel the 8 with 2 and get 4 to the numerator)
Next, we have to multiply 4/3 with 1/4,
4/3 x 1/4 = 1/3 (the 4 of the numerator of the 1st fraction gets cancelled with the 4 of the denominator of the 2nd fraction.
Therefore the answer is 1/3
