4) 0.68 ÷ 0.32= 5) 0.78÷ 0.15= solution
Answer (1)
Answer 4.( 0.68 ÷ 0.32 = 2.125 \)5.( 0.78 ÷ 0.15 = 5.2 \)Step-by-step explanation:Let’s solve each of these division problems step-by-step.Problem 4: ( 0.68 ) ÷( 0.32 )To make the division easier, we can eliminate the decimals by multiplying both numbers by 100. So, we rewrite the problem:\frac{0.68 x 100}{0.32 x 100} = \frac{68}{32}Now, we can simplify ( \frac{68}{32} ). We can divide both the numerator and the denominator by their greatest common divisor (GCD), which is 4.\frac{68 ÷ 4}{32 ÷4} = \frac{17}{8}Now, we can perform the division:17 ÷ 8 = 2.125Thus:0.68 ÷ 0.32 = 2.125Problem 5: ( 0.78 ÷ 0.15 )Again, let's eliminate the decimals by multiplying both numbers by 100:\frac{0.78 x 100}{0.15 x 100} = \frac{78}{15}Next, we'll simplify \( \frac{78}{15} \). Since there is no common divisor other than 1, we can just proceed to division.We can divide 78 by 15:78 divided by 15 goes 5 times, because:15 \times 5 = 75Subtracting:78 - 75 = 3So we have:78 ÷15 = 5 { R } 3We can express this as a mixed number:5 + \frac{3}{15} = 5 + \frac{1}{5} = 5.2Thus:0.78 ÷ 0.15 = 5.2 Final Answers:4) \( 0.68 ÷ 0.32 = 2.125 \)5) \( 0.78 ÷ 0.15 = 5.2 \)
