The product of 517 and 291 is estimated to be approximately in the neighborhood of roughly 150,447 give or take.
For a rough estimate, consider this as 500 and 300. Ignoring the zeroes, 5 time 3 is 15. Then tack the 4 zeroes removed onto the 15, giving 150,000. The figure given above is the exact answer.

30% of 291= 30% * 291= 0.3 * 291= 87.3
36% of 291= 36% * 291= 0.36 * 291= 104.76
517% as a decimal is 5.71
YOU CAN estimate it by if your product has more than 5
