Question 2 How do you write 19 50 50 19 in decimal? Answer 1 Explanation: 19 50 = 38 100 = 0.38 50 19 = 100 38 =0.38 So, 19 50 = 0.38 50 19 =0.38. Question 3 How do you write 3 1 4 3 4 1 as an improper fraction? Answer 1 Explanation: To convert a mixed fraction to an improper one, we must transfer the whole number into the numerator of the fraction. To do this, we convert the whole number 3 into a fraction with a common denominator of 4: 3 = 12 4 3= 4 12 Since 3 1 4 = 12 4 + 1 4 3 4 1 = 4 12 + 4 1 , our final step is to add the fractions together, giving us the desired improper fraction: 3 1 4 = 13 4 3 4 1 = 4 13 Question 4 How do you simplify 48 ÷ − 3 48÷−3? Answer 1 Explanation: Two negative numbers multiply to a positive number, so if you ignore the signs and divide 48 by 3, you get 16. Because the 3 is negative, the 16 should also be negative: 48 ÷ ( − 3 ) = − 16 48÷(−3)=−16 Question 5 Simplify 4 10 10 4 if it isn’t in lowest terms. Answer 1 It is not in lowest terms, as the numerator and denominator both are even numbers and they can be divided by 2: 4 10 = 2 5 10 4 = 5 2 Now, it’s in lowest terms.
