Question

Write each of the following as decimals:
(a)5/10
(b)3+7/10
(c)200+60+5+(1/10)
(d)70+8/10
(e)88/10
(f)4_2/10
(g)3/2
(h)2/5
(i)12/5
(j)3_3/5
(k)4_1/2

Answer 1

(a)5/10 = 1/2 = 0.5

(b)3+7/10 = 3 + 0.7 =3.7

(c)200+60+5+(1/10) = 200+60+5+0.1=265.1

(d)70+8/10 = 70 + 0.8 = 70.8

(e)88/10 = 8.8

(f)4_2/10 = 42/10 = 4.2

(g)3/2 = 1.5

(h)2/5 = 0.4

(i)12/5 = 2.4

(j)3_3/5 = 18/5 = 3.6

(k)4_1/2 = 9/2 = 4.5

Answer 2

Answer:

(a) 0.5 , (b)  3.7 , (c) 265.1 , (d)70.8, (e) 8.8, (f) 4.2 ,(g) 1.5 , (h) 0.4 , (i) 2.4, (j) 3.6 and (k) 4.5

Step-by-step explanation:

Explanation:

Decimal - A decimal is a number that is divided into two parts: a whole and a fraction. Between integers, decimal numbers are used to express the numerical value of complete and partially whole quantities.

• solving for $\frac{5}{10}$

                10) 50  (0.5

                      -50

                        xx

⇒ $\frac{5}{10}$ = 0.5

• Solving for  3 + $\frac{7}{10}$

On dividing 7 by 10 we get 0.7

⇒ 3 + $\frac{7}{10}$ = 3 + 0.7 = 3.7

• Solving for 200 + 60 + 5 + $\frac{1}{10}$

On dividing 1 by 10 we get, 0.1

⇒ 200 + 60 + 5 + $\frac{1}{10}$ = 200 + 60 + 5 + 0.1 = 265.1

• Solving for 70 + $\frac{8}{10}$

On dividing 8 by 10 we get 0.6

⇒70 + $\frac{8}{10}$ = 70 + 0.8 = 70.8

• Solving for $\frac{88}{10}$

On dividing 88 by 10 we get 8.8

• Similarly, $4 \frac{2}{10} = \frac{42}{10} = 4.2$
• $\frac{3}{2}$ = 1.5 , $\frac{2}{5}$ = 0.4 , $\frac{12}{5}$ = 2.4 and $3\frac{3}{5}$ = $\frac{18}{5}$ = 3.6, $4\frac{1}{2} = \frac{9}{2}$ = 4.5

Final answer:

Hence, (a) 0.5 , (b) = 3.7 , (c) 265.1 , (d)70.8, (e) 8.8, (f) 4.2 ,(g) 1.5 , (h) 0.4 , (i) 2.4, (j) 3.6 and (k) 4.5
