Answer:

see below

Step-by-step explanation:

CD = 90 - 53 = 37°

AB = 180 - 79 - 53 = 48°

ED = 180 - 37 = 143°

EB = 180 - 53= 127°

BDE = 53 + 37 + 143 = 233°

DEC = 360 - 37 = 323°°

Answer:

Part 1) $0.675\%$

Part 2) $475\%$

Part 3) $8\%$

Part 4) $\frac{67}{20}$

Part 5) $2.65$

Step-by-step explanation:

Part 1) Write as a percent 0.00675

we know that

To write a number as a percent, multiply the number by 100

$0.00675*100=0.675\%$

Part 2) Write as a percent 4 3/4

Convert mixed number to an improper fraction

$4\frac{3}{4}=\frac{4*4+3}{4}=\frac{19}{4}$

we know that

To write a fraction as a percent, multiply the fraction by 100

$\frac{19}{4}*100=19*25=475\%$

Part 3) Write as a percent 2/25

we know that

To write a fraction as a percent, multiply the fraction by 100

$\frac{2}{25}*100=2*4=8\%$

Part 4) write as a fraction 335%

we know that

$335\%=\frac{335}{100}$

Simplify

Divide by 5 both numerator and denominator

$\frac{335}{100}=\frac{67}{20}$

Part 5) Write as a decimal 265%

we know that

$265\%=\frac{265}{100}=2.65$
