Answer:
B. 10/13
Step-by-step explanation:
There are 52 cards in a deck. Divide that by 4 and get 13, thats how many diamonds there are. There are 36 number cards. Since 9 of the cards in diamonds are numbers, we dont count those ones. 13-9 is 4, so we add that to our total to get 40. 40/52 is the same as 10/13.

Answer:
1.47
Step-by-step explanation:
Use the multiplication method.
There were 10 small boxes shipped and 12 large boxes shipped.
Step-by-step explanation:
Given,
Weight of each small box = 35 pounds
Weight of each large box = 85 pounds
Total boxes = 22
Total weight of shipment = 1370 pounds
Let,
Number of small boxes = x
Number of large boxes = y
According to given statement;
x+y=22 Eqn 1
35x+85y=1370 Eqn 2
Multiplying Eqn 1 by 35
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 50
Putting y=12 in Eqn 1
There were 10 small boxes shipped and 12 large boxes shipped.

90kg of sand had been puted in 3 bags but in 2+3+7=12 parts.
90kg/12=7.5kg
Small bag has 2 parts which is 7.5kg*2=15kg
Medium bag has 3 parts which is 7.5kg*3=22.5kg
Large bag has 7 parts which is 7.5kg*7=52.5kg
2:3:7=15kg:22.5kg:52.5kg
15kg+22.5kg+52.5kg=90kg
