1.)7/10 times 2/21
2.)4/9 times 18

(1) 1/15  (2) 8

Step-by-step explanation:

(1) 7/10 x 2/21= 14/210 simplified 1/15

(2) 4/9 x 18=72/9 simplified 8

1) 7/10 * 2/21 = 14/210

14/210 simplfied is 1/15

Step by Step: Multiply Numerator by Numerator (7*2) and Denominator by Denominator (10*21). Get your answer 14/210. Divide the numerator and denominator by 14 and get 1/15.

2) 4/9 * 18 = 72/9

72/9 simplfied is 8

Step by Step: Multiply Numerator by Numerator (4*18) and Denominator by Denominator (9*1). Get your answer 72/9. numerator and denominator by 9 and get 8.

step-by-step explanation:

most likely the answer is a.

alice wins if a total of 5 is rolled. finn wins if a total of 9 is rolled.

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
