Now consider the numerators. The first fraction, two thirds, is twice as large as one third. Since one third of a quarter is one twelfth, two thirds of a quarter is two twelfth. The second fraction, three quarters, is three times as large as one quarter, so two thirds of three quarters is three times as large as two thirds of one quarter.
In statistics, the 68–95–99.7 rule, also known as the empirical rule, and sometimes abbreviated 3sr or 3 σ, is a shorthand used to remember the percentage of values that lie within an interval estimate in a normal distribution: approximately 68%, 95%, and 99.7% of the values lie within one, two, and three standard deviations of the mean ...

To become part of the Constitution, an adopted amendment must be ratified by either: The legislatures of three-fourths (presently 38) of the states; or

When a number such as 10 45 needs to be referred to in words, it is simply read out as "ten to the forty-fifth" or "ten to the forty-five". This is easier to say and less ambiguous than ...
While in 1990, 12.6 million children under age five died and in 2016, that number fell to 5.6 million children and then in 2020, the global number fell again to 5 million. [3] However, despite advances, there are still 15,000 under-five deaths per day from largely preventable causes. [ 3 ]
