Father is four times older than his son. In 14 years the father will be twice as old. What are their current ages?

wariber [46]

Answer:

---

Step-by-step explanation:

The son’s age is unknown, so call it: X

The father’s age, four times older, so that means: 4*X= 4X (I use * for multiply)

After 16 years, we add 16 to both ages:

Son: X+16

Father: 4X+16, now, after 16yrs father’s age 2x older than son:

father→ 4X+16 = 2(X+16) = 2X+32 (father twice older than the son age)

4X +16= 2X+32 (after opening the brackets)

4X-2X= 32 - 16 ——-> we moved 2X to left, turned minus -, we moved 16 to the right turned minus -

2X = 16

X = 16/2 = 8

Son’s age is 8 yrs old

Father(Sunil) age is 4x8= 32

After 16 yrs, Father’s age twice older:

8+16=24 (son)

32+16= 48 (Father,Sunil, twice older than son)

Choose the correct proportions.

kati45 [8]

Answer:

b) 5:7 = 15:21

Step-by-step explanation:

This questions tests our understanding of enlargement ratios.

#Determine the decimal equivalents or simplify to see which one is correct:

#a) 5:21 = 7:15

$\frac{5}{7}=0.7143\\\\\frac{7}{15}=0.4667\\\\5:7\neq 7:15$

#b) 5:7 = 15:21

$=\frac{5}{7}\\\\=\frac{15}{21}=\frac{5}{7} \# dividing \ by \ 3\\\\$ $\frac{5}{7}=\frac{15}{21}$

#c) 5:7 = 21:15

$\frac{5}{7}=0.7143\\\\\frac{21}{15}=1.4\\\\\frac{5}{7}\neq \frac{21}{15}$

#d) 21:5 = 15:7

$\frac{21}{15}=1.4\\\\\frac{15}{7}=2.1429\\\\\frac{21}{15}\neq \frac{15}{7}$

Hence, option b is the correct one as 5:7 = 15:21
