1. a. Convert 1 4/5 to an improper fraction by multiplying the denominator (5) with the whole number (1) then add the product to the numerator (4) to have 9/5
b. Multiply the numerators (4 and 9), and leave the denominators (5 and 5) untouched. You get 36/5 from that.
c. Divide.
36 ÷ 5 = 7 r. 1 or 1 7/5
2. a. Convert 1 5/6 to an improper fraction. You then have 11/6.
b. Now you have to find the LCM (least common denominator), which is 30.
c. Multiply the fractions. 1/30 × 11/30 = 11/30
3. a. Convert 2 2/3 to an improper fraction, and you get 8/3.
b. Find the LCM for both the denominators, it is 21.
c. Multiply 3 to 4/7 and 7 to 8/3, and you get 12/21 and 56/21.
d. Cross multiply. Diagonally find the LCM of 12 and 21, it is 4 for 12 and 7 for 21 because 12/21 × 3/3; and it is 8 for 56 and 3 for 21 because 56/21 × 7/7.
And that's all the explanation I can give for you to look over and study. Sana nakatulong naman 'to sayo at sa lahat na makikita nito :)
