How many tenths are in 5?
Reasoning could also be used to prove that if 1/5 is 2 tenths (0.2), then 2/5 would be twice as much, or 4 tenths (0.4). Students could also divide each fifth of the rectangle into 2 equal parts to make 10 tenths.
When a rectangle is divided into 10 equal parts, each part is known as one tenth or 1/10. In this rectangle, there are ten equal squares and so each square is one tenth of the rectangle. This rectangle has 3 tenths or 3/10 shaded and 7 tenths or 7/10 unshaded.
- The number 78.304 has a "7" in the tens place, an "8" in the ones place, a "3" in the tenths place, a "0" in the hundredths place, and a "4" in the thousandths place.
- Learn how to round any number off to 1 decimal place. To do this put a line in 1 number after the decimal point (after the tenths). If the number after this line is less than 5 round down, or round up if the number is 5 or above. Examples include rounding 5.3287 = 5.3, 4.2675 = 4.3, 27.1594 = 37.2 and 265.7485 = 265.7.
- If we want to round 4.732 to 2 decimal places, it will either round to 4.73 or 4.74. 4.732 rounded to 2 decimal places would be 4.73 (because it is the nearest number to 2 decimal places). 4.737 rounded to 2 decimal places would be 4.74 (because it would be closer to 4.74).
On the board or on chart paper, draw a line divided into ten equal parts. Label 0 and 1 on the number line. Ask students to locate different tenths (e.g., 5 tenths, 2 tenths, 7 tenths, 10 tenths) on the number line and to explain whether the number is closest (or equal) to 0, ½, or 1.
- Ounce – O (28 grams) You can find dispensary deals for $99 ounces, but it's typically pretty low quality. A good ounce in a dispensary will typically cost $200-300. An ounce on the street usually runs $250-$350.
- 80 quarters
- Turns out that $10 in quarters weighs half a pound. Which means one pound of quarters (which individually weigh 5.67g), naturally, adds up to $20. Handy, I thought. Looking at the United States Mint's coin specifications page, I learned that, at 2.268g per dime, one pound of dimes also equals $20.
