Which of the following numbers has the digit 5, with a place value 1,000 ? => 50004 or 5,324 or 4,325 or 52,354..
Approximation
We know that the digits of a number, one by one in order from left to right decrease in value rapidly. Let us illustrate it by examples. Mass of a gold ornament is 23.473 g. Round off to (i) two decimal places, (ii) one decimal h..

Introduction - We use specific number of digits to denote an exact value of a number for required accuracy. The digits used for such a purpose are called significant figures. Suppose a measurement is recorded as 0.6204 cm. It means that the measurem..
Summary
We use specific number of digits to denote the value of a number to a certain degree of accuracy. For a number between 0 and 1, the successive zeros after the decimal are not significant. For a number with a decimal point..

A recurring decimal is denoted by placing dots or a bar over recurring digits. Express the following recurring decimals as equivalent fractions: (a) (b) (c) (a) Let x = 0.4444 Multiply both sides by 10 ( one digit is recurring)..

Let us consider the following entries in a Students' Journal: (a) Weight of a calorimeter = 42 g (measuring instrument used is spring balance) The smallest reading the spring balance can record is 1g. There are 42 of 1 g units of measurement. Hence, there are two signi..

Tutor is an excellent. I would say this tutor is an asset of Tutor Vista.. Excellent Job!!!!!!!
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
I really liked Tutor Vista, I am confident I will get an A+ in my math test now, My sincere thanks to all the tutors -George
The tutor really touched the right methods and formulas that would help me the most as well as a helpful practice sheet to test my knowledge of the subject. Great work!
Looking for More Help!
