How can you know which equation is true? 1/2 + 3/8 = 4/10 = 2/5
———————————————

A. Because 1+3=4 and 2+8=10, this equation must be true.

B. Because 2/5 < 1/2, this equation can not be true

C. This equation must be true, because when you add fractions the sum is always less than 1/2.

D. Because 3/8 < 1/2, this equation must be true.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

happy to

pls mark as brainliest

the probability that a bird is green (.30) is true

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
