How do you calculate age problems?
Important Statements and Equations for ” Problems based on Ages”:
- If the present age is y, then n times the present age = ny.
- If the present age is x, then age n years later/hence = x + n.
- If the present age is x, then age n years ago = x – n.
- The ages in a ratio a: b will be ax and bx.
How do you solve age problems without algebra?
make two equations – considering the present age always – a + i = 42 a-11 = 3 ( i – 11) Now, solve for them – a = 26 and i = 16. The answer is a +2 i.e. 28 years.
What is twice as old?
” twice as old as” means we will be multiplying by 2.
How do you solve Father Son age problems?
The age of the father six years ago = (60 – x) – 6 years = 54 – x years. Hence, we have x = 14 years. Thus the son’s age after 6 years = (x+ 6) = (14 + 6) = 20 years. Hence the correct option is C) 20 years.
How do you solve linear equation word problems?
Writing Systems of Linear Equations from Word Problems
- Understand the problem. Understand all the words used in stating the problem. Understand what you are asked to find.
- Translate the problem to an equation. Assign a variable (or variables) to represent the unknown. Clearly state what the variable represents.
- Carry out the plan and solve the problem.
When I am as old as my father is now?
From the statement ” When I am as old as my father is now, I shall be five times as old as my son is now.” we can say: (m + d) = 5s = f: or:d = 5s – m:” By then, my son will be eight years older than I am now.
Why do students struggle with math word problems?
Word problems tend to be complicated in part because of their descriptive language. Students often don’t understand what exactly they’re being asked, especially when the problem includes abstract concepts.
Does Per mean multiply?
Subtraction-minus, greater than, take away, fewer than, less than, subtract, decreased by. Multiplication -product, multiply, multiplied by, times. Division-quotient, dividend, divide, divided by, each, per, average, divided equally. Equal-the same, equals, the same as, equivalent, is equal to.
