My friend needs help again Which of the following numbers can be expressed as a decimal that terminates? 3 over 2, 2 over 3, 3 over 4, 5 over 7 3 over 2 and 2 over 3 3 over 4 and 5 over 7 3 over 2 and 3 over 4 2 over 3 and 5 over 7

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
