Horace need to buy 0.25 more pounds of blueberry
Further explanation
7 main quantities have been determined based on international standards, namely:
- 1. Length, meters (m)
- 2. Time, second (s)
- 3. Mass, kilograms (kg)
- 4. Temperature, kelvin (K)
- 5. Light intensity, candela (cd)
- 6. Electric current, amperage (A)
- 7. Amount of substance, mol (m)
Mass is one of the principal quantities, which is related to the matter in the object (how much matter is in an object)
The main mass unit consists of 7 units of other than other units of mass such as quintals, tons, pounds, ounces:
- Kilogram, kg
- Hectogram, hg
- Decagram, dag
- gram, g
- Decigram, dg
- centigram, cg
- milligrams, mg
Each unit descends then multiplied by 10, and if one unit increases then divided by 10
Conversion of other mass units:
mg milligrams = 10⁻³ g
kg kilograms = 10³ g
µg micrograms (mcg) = 10⁻⁶ g
Mg megagrams (tons) = 10 g
ng nanograms = 10⁻⁹ g
Gg gigagram = 10⁹ g
g picogram = 10⁻¹² g
For US standart mass , the most common units are
The conversions between those units are :
1 pound = 16 ounces
1 ton = 2,200 pounds = 32,000 ounces
Horace buys [tex]{\displaystyle {2\frac {3} {4}}}[/tex] pounds of blueberries
He needs 48 ounces of blueberries for the pie
we convert ounces :
48 ounces = 3 pounds
So Horace need more blueberries to buy :
[tex]{\displaystyle 3\:-\:{2\frac {3} {4}}}[/tex]
[tex]{\displaystyle ={\frac {1} {4}}}[/tex]
= 0.25 pounds
