Answer:

x = 12°

∠A = x+23 = 35°

Step-by-step explanation:

The three angles add up to 180°.

(4x+17) + (x+23) + 80 = 180

5x = 60

x = 12°

∠A = x+23 = 35°

Write each set of fractions with the lowest common denominator and then find which fraction is greater. 4/7 and 5/8 3/8 and 4/9

Elan Coil [88]

Answer:

$\frac{32}{56}\ < \frac{35}{56}$

$\frac{27}{72} \ < \frac{32}{72}$

$\frac{20}{24}\ < \frac{21}{24}$

$\frac{9}{30}\ >\frac{8}{30}$

Step-by-step explanation:

Given that,

First set of fraction is $\frac{4}{7}\ and \ \frac{5}{8}$ .

Second set of fraction is $\frac{3}{8}\ and \ \frac{4}{9}$ .

Third set of fraction is $\frac{5}{6}\ and \ \frac{7}{8}$ .

Fourth set of fraction is $\frac{3}{10}\ and \ \frac{4}{15}$ .

Now,

Considering the first set of fraction:

LCM of 7 and 8 is 56. Now, multiply by 8 to both numerator and denominator to $\frac{4}{7}$ . and multiply by 7 to both the numerator and denominator to $\frac{5}{8}$ . We get new set of fraction as $\frac{32}{56}\ and\ \frac{35}{56}$ .

∴ $\frac{32}{56}\ < \frac{35}{56}$

Again considering the second set of fraction:

LCM of 8 and 9 is 72. Now, multiply by 9 to both the numerator and denominator to $\frac{3}{8}$ . and multiply by 8 to both the numerator and denominator to $\frac{4}{9}$ . We get new set of fraction as $\frac{27}{72} \ and \ \frac{32}{72}$ .

∴ $\frac{27}{72} \ < \frac{32}{72}$ .

Again considering the third set of fraction:

LCM of 6 and 8 is 24. Now, multiply by 4 to both the numerator and denominator to $\frac{5}{6}$ . and multiply by 3 to both the numerator and denominator to $\frac{7}{8}$ . We get the new set of fraction as $\frac{20}{24}\ and \ \frac{21}{24}$ .

∴ $\frac{20}{24}\ < \frac{21}{24}$ .

Again considering the fourth set of fraction:

LCM of 10 and 15 is 30.Now, multiply by 3 to both the numerator and denominator to $\frac{3}{10}$ . and multiply by 2 to both the numerator and denominator to $\frac{4}{15}$ .We, get the new set of fraction as $\frac{9}{30}\ and \ \frac{8}{30}$ .
