Lena found a 5/8 -carat diamond ring in the parking lot and turned it in to the police. afterward, her friends discussed the weight of the diamond in terms of decimal numbers. lena said it weighed 0.275 carats, but sheldon thought it was closer to 0.58 carats. naomi predicted the ring weighed 0.625 carats, but mark disagreed and said 0.8 carats. paula went with 0.875 carats. who had the correct measurement? a. lena b. sheldon c. naomi d. mark e. paula

Naomi had the correct measurement the ring weighed 0.625 carats

Step-by-step explanation:

* The diamond ring weighed 5/8 carats

- To know who is right lets change the fraction 5/8 to a decimal number

∵ 5/8 means 5 ÷ 8

- 5 is smaller than 8 so we will multiply it by 10 and

insert decimal point in the quotient (answer of division)

∴ It will be 50 ÷ 8 = 6 and remainder 2/8 ⇒ 1/4

∴ The quotient = 0.6 and remainder 1/4

- 1 is smaller than 4 so we will multiply it by 10

∴ It will be 10 ÷ 4 = 2 and remainder 2/4 ⇒ 1/2

∴ The quotient = 0.62 and remainder 1/2

- 1 is smaller than 2 so we will multiply it by 10

∴ It will be 10 ÷ 2 = 5 without remainder

∴ The quotient = 0.625

* Naomi had the correct measurement the ring weighed 0.625 carats
