The dromedary, or one-humped camel, was described by Linnaeus in 1758. There are no true wild dromedaries in the world today-they were domesticated between 4,000 and 2,000 B.C.E. for travel, meat and milk, and running, and became extinct in the wild around 2000 years ago.
Dividends and divisors are the two key ingredients that yield the quotient, or answer, to a division problem. The dividend is the number being divided, while the divisor is the number by which the dividend is divided. In other words, given aÃ·b, a is the dividend and b is the divisor.
Step 2: Round the divisor to the nearest ten. (The divisor is the number being divided into the number). Step 3: Replace the dividend with a number that is easy to divide by the rounded divisor. Step 4: Use mental math to divide. Step 5: Answer the question. Estimate using compatible numbers.
